PROTOCOL CONVERTER MODEL A/S-4

1. General Information

THE A/S-4 is an SNA protocol converter. It is capable of a wide variety of conversions and adaptation tasks. Listed below are just a few of the tasks the A/S-4 was designed to perform:

• Bit-oriented protocol, SDLC

• Byte-oriented protocol, ASCII

• Serial Data Transfer and Conversion

• Screen Emulation of various CRTs

• Storage of prompting commands

• Protocol conversions

• Character conversions

• Communication conversions

The A/S-4 is also designed to be easily installed and operated. The A/S-4 hardware consists of the following components:

• 16K of available Static Random Access Memory (RAM) and 32K Non-volatile Erasable Programmable Read Only Memory (EPROM).

• Two (2) Input-Output (I/O) Serial interface ports capable of the following operations:

- async, byte sync, or bit sync

- half or full duplex

- up to 19.2 bit per second data transfer

- automatic CRC generation and checking (CRC-16 or CCITT-16)

- 8 bit address recognition

- automatic zero bit insertion and deletion

- Data Terminal Equipment (DTE) or Data Communication

- Equipment (DCE) operations

- NRZI, TDI or RS232C

• Power, Data Send/Receive, and signal visual LED Indicators

• 6809 Microprocessor control

• 6 switch banks for changing RS232, NRZI, and TDI pin assignments of the serial ports

• 2 switch banks for option selections.

CHAPTER 1:General Information

The A/S-4 is a 3274 work-alike controller emulating a PU2 with one LU2 terminal and one LU1 or LU3 printer. This allows an ASCII terminal or micro computer to emulate a 3278 CRT with a 3278 printer. The A/S-4 will also emulate SNA/SDLC 3776 or 3777 work station with one LU1 console, printer, card reader, card punch, or disk. It should be noted here that for purposes of simplicity this manual refers to CRTs and PCs with the generic acronym VDU: Visual Display Unit.

Either port may be configured as data terminal equipment (DTE) or data communications equipment (DCE). This gives the system designer great flexibility in determining what type devices he will use and where the A/S-4 can be installed.

The A/S-4 is designed to ease installation by the end user. Most of A/S-4’s operating parameters (address, baud rate, ID, word structure, video display type) are “SOFT.” They may be changed from the keyboard using “Friendly” menus to step you through the set up procedure. Once programmed, the A/S-4 retains its settings in non-volatile memory until changed by the user.

CHAPTER 3: Installation

3. Installation

3.1General Installation

The A/S-4’s options are set by the operator through the use of menus and switches. The A/S-4 provides a very flexible package of options so as to work with any terminal or terminal emulating device (such as a personal computer). Due to the great numbers of options provided, it may take a little time to set up the A/S-4 unit, however once complete, the options need not be set up again. All options are battery protected for when the unit is turned off.

The A/S-4 uses external switches and easy to use menu driven Set up features.

The A/S-4 is shipped from the factory ready to run with no changes if a DTE device (VDU, Personal Computer, etc.) is attached to the A/S-4’s terminal port and the A/S-4’s modem port is connected to a synchronous modem for dial up SDLC. If this is not your application, only a few switches need be changed. Refer to Section 4.0 for switch settings of other devices.

To install the A/S-4:

1. Connect cables to devices.

2. Plug in the A/S-4.

3. Type “S” on VDU for automatic speed detection of 300, 1200, 1800, 2400, 4800, or 9600 baud

to obtain A/S-4 menus.

4. Follow A/S-4’s menus.

If you have an odd baud rate not listed, refer to Section 4.0 for setting switches for terminal baud rate. If the menus do not appear, refer to Section 13.0 for trouble shooting problems and odd installations.

3.2 Modem Interface

The modem port can be configured for several types of hardware communications. The A/S-4 is shipped with the options set for the RS232C EIA standard. The modem port can be configured for NRZI for some IBM installations by setting the switch on the rear of the A/S-4 unit to the NRZI position.

3.3 Terminal Automatic Speed Detection

The A/S-4 has the necessary hardware and software for speed detection on the terminal port. This option makes it possible to install a A/S-4 without changing a switch. Baud rates of 300, 1200, 1800, 2400, 4800, or 9600 can be detected on power up of the unit. After applying power, the operator types “S” or SNA on the terminal and the baud rate of the VDU is detected and a power up message is sent to the terminal. The “S” may be in lower or upper case, even, odd, or no parity. Switch 5 of switch bank S9 must be OFF to enable this feature to work properly. The A/S-4 is shipped with this feature ready to work.

PROTOCOL CONVERTER MODEL A/S-4

3.4 Power Transformer

The A/S-4 is shipped with a transformer for the standard USA 110-VAC outlet plug. A substitute transformer may be ordered for the for 220 VAC or other voltages. A conversion plug for different power outlets is the responsibility of the purchaser.

3.5 Synchronizer

The A/S-4 has a unique feature on the modem port to allow the A/S-4 to run SDLC over asynchronous modems, therefore providing a low cost dial up system. This is possible by the use of a hardware synchronizer circuit that derives clocks from the data. To use this feature, set the modem port switches as listed in Section 4.0 for an Asynchronous Modem.

CHAPTER 4: Switches

4. Switches

The A/S-4 is equipped with 8 banks of DIP switches, all of which are accessed from the bottom of the unit. The general functions of these switches are as follows:

Terminal Interface Configuration SW2, SW3, SW6 Terminal Speed SW6 Modem Interface Configuration SW4, SW5, SW7 Terminal Data Formats & Options SW9 Special Printer Interface SW8

NOTE

When any switches are changed, the A/S-4 must be powered off and on for the new switch settings to take effect.

6. Power Up and Configuration Menu Operations

The A/S-4 unit options are mainly set by the operator through the use of menus. The A/S-4 provides a very flexible package of options so to allow any VDU to operate like an IBM 3278 terminal and an IBM 3287 printer or a 3770 work station. Because of the great numbers of options provided, it may take a little time to set up to A/S-4 unit, but once complete, the options need not be set up again. All options are battery protected for when the unit is turned off.

6.1 Power Up

To start installing your A/S-4 unit only the VDU need be connected. Connect to VDU, making sure all the following steps have been followed.

1. Plug in, turn on, boot, or perform any other needed operation to ready the VDU.

2. Set switches SW2, SW3, SW6 on A/S-4 for type of VDU connecting to, see Section 4.2 How to set Terminal Switches for different devices. The factory default switch settings are for a VDU DTE device.

3. Set SW9 for communication options needed, refer to Section 4.5 Option Switches. The factory default switch settings are for 7 data bits, speed detection ON, menu operation ON, even parity. Be sure that SW9/6 is in the ON position: Option change on power up enabled.

4. Plug the power transformer into any standard 110 volt AC power outlet. Plug the connector on the other end of the power cord into the mating connector on the back of the unit. Insert the connector so the small beveled lip faces up for ease of insertion. The beveled lip can be inserted up or down and the unit will work fine with no harm to the A/S-4. A substitute transformer may be ordered for the A/S-4 unit for 220 volts AC or other voltages.

5. Plug an RS232-C cable from the VDU into the terminal connector on the back of the A/S-4. Pins 2-8 and 20 are required.

6. Plug an RS232-C cable from the modem or IBM host into the modem connector. Pins 2-8, 15, 17 and 20 are required.

After the above procedure has been completed, the A/S-4 should have three lights on, the power, TCTS, and TCD. If these lights are not all on the A/S-4 unit will not communicate with the VDU host properly. Refer to Section 11.0 Trouble Shooting Problems and Odd Installation Problems if all three lights will not come on.

With all three lights on, the A/S-4 is waiting for the letter “S” from the VDU for auto speed detection if the option is enabled. The operator types lower or upper case “S” and the A/S-4 will calculate the baud rate and send out a power up message. The A/S-4 is capable of detecting baud rates of 300, 1200, 1800, 2400, 4800 and 9600. If the speed detect option is off, the A/S-4 will send out the power up message two or three seconds after the three lights come on at the baud rate set by switches SW6 (refer to Section 4.1 Terminal Switches). If the power up message does not look like Figure 1, check the option switch SW9 or refer to Section 13.0 Trouble Shooting Problems and Odd Installation Problems. If the message “MEMORY ERROR U13 or U14” is displayed, refer to section 13 to determine if the A/S-4 is defective.

CHAPTER 6: Power Up and Configuration Menu Options

6.2 Power Up Message

The A/S-4 sends out the message in Figure 1 on power up or the raising of DTR (DATA TERMINAL READY) on the terminal device. This message informs the operator that the A/S-4 is ready to try to match the operator’s terminal or terminal emulation package with the VDU (VISUAL DISPLAY UNIT) list in the memory. The operator may now type the “HOME” key on his/her terminal so that the A/S-4 may match the VDU device with the internal VDU list so that the clear screen, home cursor, position cursor commands, etc. to the VDU will be correct. If no match occurs, the A/S-4 defaults to the IBM 3101 VDU command set. This is not a problem if your VDU is not an IBM 3101, as you may change the VDU by the use of menus. If your terminal does not have a home key, you may hit the space bar and set up the VDU by the menus. Hitting the space bar leaves the internal VDU the same as the last VDU used with the A/S-4. After typing “space” or “HOME” the A/S-4 will output the A/S-4’s main menu. If a VDU match did occur, the screen will clear before the main menu is displayed, otherwise the VDU device will scroll.

PROTOCOL CONVERTER MODEL A/S-4

6.3 A/S-4 Main Menu

A set of menus are used to configure the A/S-4’s options so that it will operate properly with the particular VDU and host to which it is connected. In order to access these menus, SW9/6 must be in the ON position (see Section 4.5). All options are stored in battery-protected RAM so that they need not be reconfigured in the event of interruption of AC power to the unit.

At the beginning of every A/S-4 menu are the current main three options, the application, VDU and keyboard. The application option informs you of which keyboard layout the A/S-4 will use when running SDLC/SNA.

The A/S-4 Main Menu is shown in Figure 2. This menu coordinates the changing of the many A/S-4 options into main categories, VDU Selection, VDU commands, VDU video commands, keyboard selection, keys on keyboard arrangement, application, application options, printer options and verification of switch settings.

6.4 Switching from A/S-4’s Main Menu to Running the Application

Once all operating parameters have been configured properly, the A/S-4 is ready to run. To connect the asynchronous devices to the application, enter the letter “A” for the RUN option of the A/S-4’s Main Menu. The A/S-4 will then proceed to connect up to the application in one of the following manners depending on which of the three states the host communication line is in:

1. Modem not ready; if the modem is turned off or on a dial up line the modem has not been dialed or on a lease line the line is down, the A/S-4 will display on the VDU “DIAL UP SDLC LINE”. Once the phone line connection with the host has been establish the A/S-4 will proceed to one of the following two states. Refer to Section 13.0 on Trouble Shooting if the Dial Up message will not go away for more information.

PROTOCOL CONVERTER MODEL A/S-4

2. Modem connected to host but LU inactive; if the LU is inactive the A/S-4 will display “WAITING FOR LU TO COME ACTIVE”. The LU should come active after a few seconds of this message appearing on the VDU. If the LU does not come active, then one of the following problems may exist:

A. Host is not polling PU (Physical Unit) Solution: Have a network operator activate

the PU and maybe the line also.

B. PU address (or station address) is incorrect Solution: Return to A/S-4 menus and

change PU address.

C. LU address is incorrect Solution: Return to A/S-4 menus and change LU address.

After the LU comes Active, the A/S-4 will proceed to the following state. Refer to Section 13.0 on Trouble Shooting if the LU will not activate for more information.

NOTE

In states 1 and 2 typing any key will return A/S-4 to it’s Main Menu

3. Application running:

Interactive - The A/S-4 will refresh the VDU’s screen with the last screen received from the host (which could be blank). Operation will then function as a 3278 CRT.

Batch - The A/S-4 will display the status of the LU on the status line but no previous data from the system will be displayed on the VDU. Operation will then function as a 3770 work station.

CHAPTER 6: Power Up and Configuration Menu Options

6.5 Changing the VDU Type

If the current VDU type displayed at the top of the A/S-4 Main Menu does not match the VDU or VDU emulation package you have connected to the A/S-4, you may change the VDU type by entering the letter “B” in response to the Main Menu. The change VDU Menu will then be displayed on your screen as in Figure 3. If your screen is scrolling A/S-4 menus instead of clearing the screen before each menu, then you should change the VDU type. The change VDU menu allows you to match your VDU with one of the A/S-4’s fixed VDU types or to create a new A/S-4 VDU type. The A/S-4 feature for creating a new VDU type allows A/S-4 to work with any asynchronous device with screen capabilities.

The change VDU menu allows 4 operations as described below:

1. Exit - By entering the number 1 or the letter A the A/S-4 will return to the Main Menu with the VDU type currently at the top of the screen.

2. Change current VDU type at top of screen - By entering the number 2, the operator may change the VDU type. The A/S-4 will then display “ENTER LETTER:” so that the operator may select the letter preceding the desired VDU type from the list of programmable and fixed VDU types. Fixed VDU types have the VDU commands characters hard coded into the A/S-4’s firmware and require that your VDU or VDU emulator match those commands character for character. Programmable VDU types have VDU command characters stored in battery protected memory so that command characters in the A/S-4 can be changed to match the operator VDU or VDU emulator that is not exactly like any of the Fixed VDU types. After the operator enters the desired letter (A thru J), the menu will redisplay with the new VDU type at the top of the screen using the new command character set of the selected VDU.

PROTOCOL CONVERTER MODEL A/S-4

NOTE

Selection of a blank programmable VDU type may cause erroneous command characters to be sent to the operators VDU. The programmable VDU type should be added by option 3 before it is selected.

3. Add or Change Name - by entering a 3 the operator is able to add a name to or change a name from the “PROGRAMMABLE” column see figure 4. This is done when the operator’s VDU does not match one of the “FIXED” VDU’s and it allows him to define to the A/S-4 the various commands his VDU needs to operate properly (e.g., the command from the A/S-4 which will cause his VDU to clear the screen). In the example shown in figure 4, the operator has given the name “NEW VDU” to VDU A. Operator input is underlined. The 10 characters are filled out with spaces or just type carriage return. By typing the letter “H”, he has copied the characteristics of VDU H into those of “NEW VDU”. The “CURRENT” header will now show the VDU as “NEW VDU”. Using the VDU commands menu (selection C on the Main Menu) he can now change the clear screen command (or any other command) from the command copied from VDU H to whatever “NEW VDU” needs (these commands may be found in the NEW VDU manual).

4. Delete Name - By entering a 4 the operator can delete a name from the “PROGRAMMABLE” VDU list.

6.7 Changing Video Attributes and Commands for VDU

The menu obtained by selecting item D of the main menu is shown in Figure 7. This menu allows the operator to define the parameters which will give the proper video highlighting to the fields on the VDU screen.

Enter Letter:

Figure 7

The host CPU can send commands to its terminals to define how the video display will be printed. An example is a display using highlighted areas for data entry. The A/S-4 can perform this type of display presentation for almost any terminal. In operation the A/S-4 intercepts the host video commands and translates them into the commands that the attached VDU needs to perform the function. If you are using special displays then you must use selections B, C and D to set up your display attributes. Consult your VDU users manual to determine which characters are used to create the type display you need and enter those characters in the fields as needed.

CHAPTER 6: Power Up and Configuration Menu Options

The general format of a video command to a VDU is as follows:

ESC X Y Z

Start of video cmd. Middle of video cmd. nd of video cmd.

X, Y and Z represent ASCII characters. The end of video command may not be necessary and therefore displayed as a blank. Items B, C and E through M can be defined using the format shown above.

Item D differentiates between two techniques of video highlighting: 1) The video command occupies a space on the screen and defines the start of a video highlight field (e.g., Televideo 925). 2) The video command does not occupy a space and does determine the type of video highlight for all subsequent received characters, regardless of their positions on the screen (e.g., DEC VT100).

Video types referred to in figure 7 correspond to the video highlighting codes which are sent to the A/S4 from the IBM host. It is up to the operator to enter the proper value for the middle of command to match (or mismatch, if desired) each video type.

If no video highlighting is desired, the operator may turn off (prevent the A/S-4 from sending video commands) this feature by entering a space for Item B, start of video command. The A/S-4 assumes if there is no start command, than there is no video commands for the VDU.

By selecting E from the main menu, the menu shown in Figure 8 is obtained. This is used to select the specific keyboard mapping the operator desires. Selection of F, G and H provide fixed keyboards shown on the previous pages. Programmable keyboards may be added as any of the selections A through E. By using a programmable selection, the operator can design the keyboard to his or her liking.

To change the keyboard used enter 2 then select the keyboard layout you desire from those listed.

If you prefer an unlisted keyboard type you should select one of the letters under programmable and enter the name (10 characters max). If the name is less than ten characters long, type carriage return or spaces to complete the ten character name. If your keyboard looks like one of the fixed keyboards then you should enter its letter as a response to “make new keyboard look like established name”.

NOTE

Selection of a blank entry from the programmable list may cause the A/S-4 to malfunction.

Names of programmable keyboards may be added, changed, or deleted by using selection 3 and 4.

If a programmable keyboard has been selected, the operator should now set up the keys arrangement as he or she wishes using selection F from the A/S-4’s main menu.

The change Application menu allows 8 operations as described below:

A. Exit - By entering the letter A the A/S-4 will return to the Main Menu.

B. XID - By entering a B the operator is able to change the A/S-4 SDLC control unit identifier. Only

hexadecimal numbers are allowed to be entered for this selection, the first two digits are fixed at 01. The next character indicates what type of device the A/S-4 (7=3274, 8=3276, 0=3774, 1=3774P, 2=3771 and 3=3776/77).

C. PU Addr - To change the units physical unit address enter C. Only hexadecimal numbers are allowed

to be entered for this selection; addresses x’00’-SSCP address and x’FF’-Global SDLC address can not be used.

D. SDLC Baud Rate - By entering a D the operator can select the baud rate at which the host will

transmit and receive data from the A/S-4. This selection is only used when running SDLC over asynchronous modems or when the A/S-4 is supplying clocks to a front end processor. After entering the letter D the current baud rate will be displayed. To change it, enter the letter Y which will scroll pass each selectable baud rate, when the correct rate is displayed entering any key other than the Y will save the new baud rate.

NOTE

SDLC baud rate has no effect when running with synchronous modems.

E. XON/OFF - Entering an E allows the selecting of the DC1 (XON), DC3 (XOFF) protocol on the

A/S-4’s terminal port. This protocol can be used; TO the unit or FROM the unit or in BOTH directions. To disable the XON/OFF protocol, select the option for OFF by the use of the letter Y, entering any key will save the selection. This protocol is used so the A/S-4 or the attached async device will not overflow each others buffers with data. If the A/S-4 has room to store only 20 characters from the VDU, the unit will drop it’s RTS signal (can be connected to pin 4, 5, 11, 19 or 20 of EIA connector) and send an XOFF character if option is set for FROM or BOTH. When the A/S-4 is sending data to the VDU, the VDU can stop the flow by dropping it’s signal connected to the A/S4’s CTS or by sending a XOFF character, if the A/S-4’s XON/XOFF option is set for TO or BOTH.

F. VDU LU Addr - The VDU LU address can be changed by entering the letter F. For this selection only

hexadecimal numbers are allowed to be entered, from the range of X’01’ to X’FF’ but for most installations the address range of the specific type of control unit is as follows:

IBM* 3274 = X’02’-X’21’ IBM* 3276 = X’02’-X’09’ IBM* 3776 Model 3 and 4 = X’01’-’06’

NOTE

Do not set the VDU and PRT LU addresses to the same values.

CHAPTER 6: Power Up and Configuration Menu Options

G. PRT LU Addr - By entering a G the operator can select which LU’s data will go to the printer

attached to the A/S-4’s terminal port. Selection of this address is done the same as for the VDU LU addr above.

H. PRT LU Type - The printer LU type is changed by entering the letter H which causes the LU type to

toggle between type 1 and 3. Type 3 print data is preceded with a Write command followed by a WCC with the start printer bit set. Type 1 data doesn’t have this Write command or WCC in its data.

6.11.2 CHANGING BATCH APPLICATION OPTIONS

The change Application menu allows 16 operations as described below:

A thru G - are the same as for changing Interactive options, refer to section 6.11.1 for details.

H. Start of File - By entering an H the operator can select the first character that must be received from

the VDU before any data is stored and then transmitted to the host. This character is also the first character sent to the VDU when data is received from the host. This is a single character command that can be a control character displayed as CTL or a printable character. The Start of File character can be disabled by setting it to a null X’00’ or space character.

I. End of File - This single character command that causes the VDU to terminate the transmission of

data to the host and is received by the VDU when an end of message, is received from the host can be changed by entering an I. This command is selected and disabled the same as the Start of File character described above.

J. Send FMH-2 to VDU - Option can be toggled on or off by entering the letter J. When this option is

enabled “YES” a Function Management Header-2 received from the host is sent to the VDU, for complete details refer to Section 8.1 on Batch operation.

K. Precede TRN Ctl Chars with DLE - By entering a K, this option can be toggled on or off. This causes

transparent control characters (X`3F’ or less) received from the host to be made a printable ASCII character by setting its two most significant bits. This character then would be preceded with a DLE character (X`10’) before being sent to the VDU if option is set for “YES”. This option also determines if data received from the VDU will be preceded by a DLE if the character is less than a X`20’ space character.

L. Echo Input - By entering a L the operator can toggle this option on or off if he would like all

characters transmitted by the VDU to the A/S-4 sent back to the VDU.

M. Card Input Data Only - Option can be toggled on (“YES”) by entering an M, which would cause all

data received from the VDU to be transmitted to the host in card format by the inbound (VDU) LU. With this option on, no device indicator should be sent to the VDU. When this option is off (“NO”), data received from the VDU must be preceded by a device indicator which determines what device (console, card, printer or disk) is sending the data to the host. Refer to section 8 for more information on the device indicator. With option on, only the inbound (VDU) LU can send data to the host so both LU’s must be set for Auto Logon to become active with the application (e.g. JES2).

CHAPTER 6: Power Up and Configuration Menu Options

N. VDU Auto Logon Msg - This 80 character message can be changed by entering the letter N followed

by the Logon message, containing any printable ASCII character (X`20’-X`7F’). The field separator (X`1C’) character, which is used to delimit the different logon strings for the VDU LU and the PRT LU. The carriage return (X`0D’) character is used to indicate the end of the logon message. The auto logon is enabled whenever any data is present in the logon message. To disable auto logon, enter a carriage return as the first character of the message. This logon message will be sent to the host by the VDU (inbound) LU when this LU becomes active. All data except the CTL\’s (field separators) will be sent.

O. PRT Auto Logon Field - This 10 character field can be changed by entering the letter O followed by

the logon field, containing any printable ASCII character (X`20’-X`7F’). The carriage return (X`0D’) character terminates the end of the field. This field if selected, will cause an auto logon message to be sent by the PRT (outbound) LU when the PRT LU becomes active. The logon message will be the same one as for the VDU LU except the data enclosed by CTL\’s will be replaced with the PRT auto logon field. The PRT logon field is disabled by entering a carriage return as the first character of the PRT logon field.

P. VDU/PRT Auto Signon Msg - This 80 character message can be changed by entering the letter P

followed by the signon message, containing any printable ASCII character (X`20’-X`7F’). This carriage return (X`0D’) character terminates the signon message. This message if selected, will be sent by the VDU LU and PRT LU to the host after a LU-to-LU session is established for the respected LUs. Entering a carriage return as the first character of the message will disable the auto signon.

NOTE

The auto logon and signon messages cannot contain any character used only in

EBCDIC (e.g. cent character X`4A’).

6.12 Printer Options

Selection of item I from the main menu will cause the menu in Figure 17 to be displayed. This menu is used to select default printer settings for the printer attached to the A/S-4. Selection of B, C and D are considered programmable in that the host computer can send:

1. Set Horizontal Format (SHF) command to change the B- Column Width.

2. Set Vertical Format Density (SVF) command to change C-Lines Per Page

3. Set Line Density (SLD) command to select a different D-Lines Per Inch.

PROTOCOL CONVERTER MODEL A/S-4

These new values, if received from the host would then be sent to the printer if the G-Start Char-FORMS or K-Start Char-DENSITY are selected.

The Printer Options menu allows 13 operations as described below:

A. Exit - By selection the letter A the A/S-4 will return to the main menu.

B. Column Width (xxx) - This value is used to define the length of a print line and can be changed by

entering the letter B, followed by any decimal number value from 001 to 255. An entry larger than 255 will set the column width to a value less than 255. The host set Horizontal Format (SHF) command can temporarily change the column width used by the printer with the MPP (maximum print position) value enclosed in the SHF command. This new MPP value will not be displayed in the Column Width option. Refer to Section 8, Batch operation for more details.

C. Lines Per Page (xxx) - Indicates the number of print lines per page (page depth) and is changed by

entering the letter C, followed by any decimal number value from 001 to 255. Any entry larger than 255 will set the lines per page to a value less than 255. The host Set Vertical Format (SVF) command can temporarily change the lines per page used by the printer with the MPL (maximum presentation line) value enclosed in the SVF command. This new MPL value will not be displayed in Lines Per Page option. Refer to Section 8, Batch operation for more information.

CHAPTER 6: Power Up and Configuration Menu Options

D. Lines Per Inch (xxx) - By entering the letter D, followed by any decimal number from 001 to 063, the

operator can change the lines per inch (LPI) the printer will print. If a decimal value larger than 063 is entered, the LPI option will be set to a value less than 063. The host Set Line Density (SLD) command can temporarily change the lines per inch used by the printer. This new LPI value will not be displayed in the Lines Per Inch option. See Section 8, Batch operation for more information.

E. Single/Double Space - Option can be toggled from Single (NL x`15’ received from host send CR LF

to printer) to Double (NL x `15’ received from host send CR LF LF to the printer) line spacing.

F. MONO/Dual Case - By entering an F the operator can toggle from Dual (upper and lower case

characters sent to the printer) to MONO (only upper case characters are sent to the printer, if a lower case character is received from the host it is converted to upper case).

The following commands are sent to the attached printer to change or set the printer for the selected parameters:

G. Start Char-FORMS - This two character command can be changed by entering the letter G followed

by any ASCII control character (X`00’-X`20’) for the first character and any ASCII character for the second one. Entering a space character as the first character of the command will disable this option. The Start character is used in conjunction with the multiple, separator and final forms characters to change or set the attached printer’s programmable settings, refer to section 6.12.1 for details.

H. Multiple -xxx- Three character command can be changed by entering the letter H followed by a

space or any decimal digit 0 - 9. Entering a space as the first character will turn off this option. This option in conjunction with the Start Char-FORMS, Separator and final forms character can change or set the printer’s programmable settings. The Multiple value is also used with the Start CharDENSITY, Separator and final density characters to change or set the printer’s lines per inch setting. Refer to Section 6.12.1 for details.

I. Separator Char - By entering the letter I followed by a single ASCII character will change the character

sent after the Start FORMS character to set the printer’s programmable settings. The separator character will not be sent if set for a null (CTL @), this can be done by using the terminal’s Break key. Refer to Section 6.12.1 for details.

J. Final Char - This single character value is sent after the Forms Separator character to set the printer’s

programmable settings. The final character may be changed by entering the letter J followed by any ASCII character. This final character is disabled by setting it to a null (CTL @). Refer to section

6.12.1 for more information on setting printers forms.

K. Start Char-DENSITY - This two character command can be changed by entering the letter K followed

by any ASCII control character (X`00’-X`20’) for the first character and any ASCII character for the second one. Entering a space for the first character of the command will disable this option. The Start character is used in conjunction with the multiple, separator and final density characters to change or set the attached printer’s lines per inch setting, refer to Section 6.12.1 for details.

L. Separator Char - By entering the letter L followed by a single ASCII character will change the

character sent after the Start density character to set the printer’s lines per inch setting. The separator will not be sent if set for a null (CTL @). Refer to section 6.12.1 for description of command usage.

M. Final Char - This single character value, sent after the density separator character to set the printer’s

lines per inch setting, may be changed by entering the letter M followed by any character. This final character is disabled by setting it to a null (CTL @). See Section 6.12.1 for details on operation.

PROTOCOL CONVERTER MODEL A/S-4

PROGRAMMABLE PRINTER OPTIONS

Print data received from the host or printed by a local print function will be formatted by the values set in the Printer Options menu (e.g. Column Width, Lines Per Page, Single spacing). The A/S-4 is capable of having numerous printer options changed while communicating with a host program. When the printer is an LU type 3, the only change possible from the program is the number of characters printed per line. This is defined in the write control character (WCC) of the printer message. For an LU type 1, many changes are possible by the use of SNA Character String (SCS) control codes described below:

a. Set Horizontal Format (SHF) command defines the maximum presentation position (MPP),

the left margin (LM), right margin (RM) and up to six horizontal tab stops for a page of print. At the present time, the only value passed on to the printer by the A/S-4 is the MPP (column width) and is done so by the use of the FORMS commands set up in the Printer Options menu. When the SHF is received, the new values override any default values set by the printer option menu and the new forms value is then sent to the printer. If the Start Char-FORMS is disabled, the new values are not sent to the printer.

The following is an example of setting the printer for a 80 column page:

ESC, F, 8, 0 - OKI Microline 83A command to set 80 column page

Printer Options Menu settings:

G-Start Char-FORMS=ESC F H-Multiple - (`xxx’ X inches)-xxx=001 I-Separator Char=CTL @ J-Final Char=CTL @

b. Set Vertical Format (SVF) command defines the maximum presentation line (MPL), top

margin (TM), bottom margin (BM) and up to six vertical tab stops for a page of print. At the present time the only value passed on to the printer by the A/S-4 is the MPL (lines per page) and is done so by the use of the Forms commands set up in the Printer Options menu. When the SVF is received the new values overrides any default values set by the printer option menu and the new forms value is sent to the printer. If the Start Char-FORMS is disabled, the new values are not sent to the printer.

The following is an example of setting the printers page length of 11 inches.

ESC,[,7920r - GENICOM 3000 command to set 11 inch page

Printer Options Menu settings:

G-Start Char-FORMS=ESC [ H-Multiple - (`xxx’ X inches)-xxx=720 I-Separator Char=CTL @ J-Final Char=r

c. Set Line Density (SLD) specifies the (LPI) distance to be moved for a single line (vertical

spacing), as in NL or LF. When the SLD is received the new value overrides any default lines per inch (LPI) value set by the printer options menu and the new LPI value is then sent to the printer. If the Start Char-DENSITY is disabled, the new values are not sent to the printer.

CHAPTER 6: Power Up and Configuration Menu Options

The following is an example of setting the printer for 8 lines per inch.

ESC, 8 - OKI Microline 83A command to set 8 LPI

PROTOCOL CONVERTER MODEL A/S-4

The Verify Switch Settings menu allows 2 operations as described below:

A. Exit - By entering the letter A the A/S-4 will return to the Main Menu.

B. Restart With New Switch Options - When a B is typed and he A/S-4 will start over, just like the

power has been turned off and then on. When the A/S-4 goes through power up, all switches displayed in the menu will be read and serviced.

The Verify Switch Settings menu will display any change in the switches in the menu. The change in the switch should be followed by the Restart command B to insure that the change has been acted upon.

NOTE

The Verify Switch Settings menu will be displayed when running with the A/S-4 PC card, but the switches have no effect on the program running in the PC card because there are no switches on the PC card, so the values displayed for the switches is actual data read from the PC memory.

6.14 Reload Default Options

By selecting item K from the main menu (Section 6.3), the operator obtains the screen shown in Figure 19 which in turn can change all the options in the A/S-4 to their defaults. Entering any character other than a “Y” will return to the main menu without changing any options, if a “Y” is entered the A/S-4 will go through its power up routine as if the power to the unit was turned off and then on.

Reload Default Options

If sure type Y (ALL PAST WORK WILL BE LOST!)

Figure 19

Refer to section 8.4 of Batch operation for the A/S-4’s default options settings.

CHAPTER 7: Interactive Operation

7. Interactive Operation

The A/S-4 operating in the Interactive mode, emulates an IBM 3274/76 cluster controller with a single LU Type 2 terminal IBM 3278 and an IBM 3287 LU Type 1 or 3 printer. The VDU LU assigned by the HApplication Option menu is the terminal’s (IBM 3278) logical unit and the PRT LU is the printer’s (IBM

3287) logical unit. With the combination of these two LUs the CRT operator can have a job being printed out on the printer while doing other interactive work with the terminal simultaneously.

As described in Section 6.4 on the actual running of the A/S-4 after all menu items are selected the “WAITING FOR ACTIVE LU” message will be displayed on the terminal. After the LUs become active the operation of the unit is dependent on the SNA host it’s communicating with, so no further description of operation is needed.

NOTE

For the Interactive screen to be displayed correctly, the CRT must be selected to disable cursor auto wrap. If a character is in column 80, the cursor will not advance to the next line.

PROTOCOL CONVERTER MODEL A/S-4

8. Batch Operation

The A/S-4 operating in the Batch mode, emulates an IBM 3776/77 Model 3 and 4 multiple logical unit (MLU) work station with a console, printer, card reader/punch and exchange diskette attached. The A/S-4 supports two of the six possible logical units available for a MLU work station. The VDU LU is designated as the inbound (to host) logical unit and the PRT LU is the outbound (from host) LU. The VDU LU will reject data from the host for the printer, card reader or exchange diskette by sending a negative response to the function management header, which indicates the data is for any of the above devices. The host will then send the data to the PRT LU. This insures that at least one LU will be free to send jobs or console commands while receiving data from the host. Console data is the only data the VDU LU will accept while the PRT LU will receive host data from all devices.

The following is the step by step procedure used by the A/S-4 after the “WAITING FOR ACTIVE LU” message is sent out for Batch operation. Refer to Section 6.4 for steps before ACTIVE LU message.

1. With the “WAITING FOR ACTIVE LU” message displayed, entering any character other than an SO (X`0E’) or SI (X`0F’) will cause the main menu to appear again if SW9/6 is in the ON position (change options on power up). Entering of the SI (X`0F’) command will cause the status of the PU and LUs to be displayed as described in section 8.1. Receipt of an SO (X`0E’) followed by X number of characters will change the A/S-4’s options and cause it to start over from power up. Once one of the LU’s become active a new line status will be displayed.

2. When one or both LUs become active the A/S-4 will send a clear screen command, display the current line status and try to do an Auto Logon if selected for the active LU. The Auto Logon message will be displayed if the Echo Input option is enabled. If no Auto Logon is selected and the host system does not auto-BIND the LUs, the console operator must logon both LUs before the application (e.g. JES2) can communicate with the work station. The device selection character (Section 8.2) must be selected for the inbound LU on one logon message and then set for the outbound LU on the next so both LUs are logged on to the application.

3. When one or both LUs are bound up to an application (e.g. JES2) and receives a set data traffic command, the A/S-4 will display the current line status and send the Auto Signon if selected for the LU in LU-to-LU session. The Auto Signon message will be displayed if the Echo Input option = YES. Once the Auto Signon is sent, jobs and console commands can be sent and received from the host. For the description of inbound data see Section 8.1 and for outbound data refer to Section 8.2.

CHAPTER 8: Batch Operation

8.1 Receiving Batch Data from the SNA host

When SNA data is received from the host by the A/S-4, the data is sent to the VDU as follows:

Start Special End of

VDU CMD Device On of File Control File VDU

1 2 3 STX 4 5 Data 6 ETX 1

CMD Device Off

1. VDU CMD or CRT lead in character is selected by C-VDU commands menu. This single or dual character command is not sent to the VDU if the Device ON command is selected for a control character (X`1F’ or less) or disabled by being set to a space.

2. Device (Printer, Card, Disk) On is selected by C-VDU commands menu. This single or dual character command directs the received SNA data to the correct device; printer, card or disk. This command can also be disabled (turned off) by setting it to a space so that no Device On is sent. If the command is set to a printable character (X`21’ or greater) the VDU CMD will precede the Device On command.

NOTE

Console data is not preceded by a VDU CMD or a Device On character.

3. Start of File (SOF) character is selected by H- Application Options menu. This single character command can be disabled (turned off) so that no Start of File character is sent.

4. Special Control (SC) characters precede some types of data mentioned below:

a. SOH ($01) character indicates that a Function Management Header-2 follows. The FMH-2

data is sent to the VDU without converting the SNA EBCDIC data to ASCII (transparent mode) inserting DLE’s before ASCII control characters if needed. The VDU CMD and device selection are sent along with this message if selected.

PROTOCOL CONVERTER MODEL A/S-4

b. SI ($0F) character precedes the SNA line status report of each logical unit. This line status

is handled as console data so the VDU CMD and device selection are not sent along with this message. The line status is reported as follows:

SOF SC 1 2 3 4 EOF

STX 0F 3 3 CR LF LU, LU CR LF ETX

Character Number:

1. 0 ($30) Physical Unit (PU) not active

1 ($31) PU active but inbound logical unit (LU) not active 3 ($33) Inbound LU active but no LU-LU session active 7 ($37) Inbound LU active and in session with another LU

2. 0 ($30) PU not active

1 ($31) PU active but outbound LU not active 3 ($33 ) Outbound LU active but no LU-LU session active 7 ($37) Outbound LU active and in session with another LU

3. DW = PU not active

PU = PU active LU = Inbound LU active-can send logon or receive SSCP data LL = Inbound LU in LU-LU session-can send or receive jobs

4. DW = PU not active

PU = PU active LU = Outbound LU active-can send logon or receive SSCP data LL = Outbound LU in LU-LU session-can send or receive jobs

5. Normal EBCDIC data received from the SNA host will be converted into ASCII before being transmitted to the VDU. Transparent Data received from the SNA host will be passed to the VDU with no conversions, except when the character is less than a hexadecimal value of $20. The character would then be preceded by DLE ($10) and the character itself would be made ASCII printable by setting it’s two most significant bits. This addition of the DLE and making the character printable is only done if this option is selected in the Application Options. Example: Recvd - $1E = $10$DE - Xmitted

6. End of File (EOF) character is selected by H-Application Options menu. This single character command can be disabled (turned off) so that no EOF character is sent.

7. Device OFF is selected by C-VDU commands menu. This single or dual character command terminates the transmission of this device’s data. This command can also be disabled (turned off) by setting it to a space so that no Device Off command is sent. If the command is set to a printable character (X`21’ or greater) the VDU CMD will precede the Device OFF command or if the Device OFF is set to a control character no VDU CMD will precede it.

NOTE

Console data is not terminated by a VDU CMD or a Device OFF character.

CHAPTER 8: Batch Operation

8.2 Transmitting Batch Data to the SNA Host

To send data to the SNA computer, the data from the VDU should look like this:

Device

Selection

Start or End

of Special of

File Control File

1 STX 2 3 Data 4 ETX

1. Start of File (SOF) character is selected by H Application Options menu. This single character command can be disabled (turned off) so that no SOF character needs to be received before handling the incoming data from the VDU.

2. a Device selection character indicates which device (card, disk, printer or console) the data

is from, if the data is in transparent form and which Logical Unit (LU) should transmit the data to the SNA host. This character is not sent to the SNA host. The following is the Device Selection character with its assigned bits:

Bit 7 6 5 4 3 2 1 0

11 Y X X

1 = Outbound LU data

0 = Inbound LU data 1 = Transparent data XX = 00 - Console Data 0 = Normal data 01 - Disk Data

10 - Card Data

Parity bit can be 0 or 1 11 - Printer Data

Y = Do Not Care

Example: Device selection character of “2”(X`32’) would cause the data to transmit to the SNA host as normal card data by the inbound (VDU) LU.

2.b Special Control (SC) character precedes some types of data mentioned below:

1) SO(X`0E’) character readies the A/S-4 to receive new options following the SO character. For this to work, the A/S-4 and the VDU must be set for a character length of 8-data bits with no parity. The contents of this string of options is described later. The SO (X`0E’) character does not need to be preceded by the Start of File character or followed by an End of File character.

PROTOCOL CONVERTER MODEL A/S-4

2) SI (X`0F’) character asks the A/S-4 for the SNA line status of each Logical Unit. The response to the SI is described in the transmission of the SI character as a special control character. Any data following the SI character will be thrown away until a Start of File is received. The SI (X`0F’) character does not need to be preceded by the Start of File character or followed by an End of File character.

3. Normal ASCII data received from the VDU will be converted into EBCDIC before being

transmitted to the SNA host computer. This received data will be checked for end of record characters (CR, LF, CRLF and RS) and trailing spaces. Trailing spaces in a record will be truncated. If no end of record character is found after receiving eighty characters, the A/S-4 will insert an end of record character and truncate any trailing blanks before transmitting the record to the SNA host. Transparent data received from the VDU will be passed to the SNA host with no changes, except when the Precede TRN Ctl Chars with DLE option is selected and a DLE followed by another character is received. When this occurs the DLE character is thrown away and the following character’s two most significant bits will be changed to zero’s. For transparent data to work correctly without the DLE option enabled, both the VDU and the A/S-4 must be set for 8-data bits with no parity and XON/XOFF throttle turned off.

4. End of File (EOF) character is selected by H-Application Options menu. This single character

command terminates the transmission of the VDU data. This command can also be disabled (turned off) so that no EOF character is sent, but if disabled all data received may not be sent to the host.

8.3 Batch Printer Operation

Data received from the SNA host directed to the printer device by the use of the function management header - 1 (LU Type 1) or by the write control character (WCC) (LU type 3) is handled differently than card, console or disk data. This printer data is inspected for SNA Character String (SCS) control codes, space characters and transparent data indication. Most of the SCS codes are single character commands (e.g. NL, BS, LF) which are converted into their ASCII equivalent (see appendix C), but a few SCS commands are two or more characters long which are handled as described below:

1. Set Horizontal Format (SHF) command defines the maximum presentation position (MPP),

the left margin (LM), right margin (RM) and up to six horizontal tab stops for a page of print. This command is used internally by the A/S-4. The printer may receive new operating conditions depending on printer options selected. Refer to Section 6.12.1, Programmable Printer Options for details.

2. Set Vertical Format (SVF) command defines the maximum presentation line (MPL), top

margin (TM), bottom margin (BM) and up to six vertical tab stops for a page of print. This command is used internally by the A/S-4.The printer may receive new operating settings depending on printer options selected. Refer to Section 6.12.1 for details.

3. Set Line Density (SLD) defines the distance to be moved for a single line (vertical spacing), as

in NL or LF. This command is used internally by the A/S-4, the printer may receive a new lines per inch (LPI) setting depending on printer selections. See Section 6.12.1 for details.

4. Vertical Channel Select (VCS) selects one of 12 vertical channels to control vertical formatting

of the page. This two character command causes a line feed (LF) to be sent to the printer.

CHAPTER 8: Batch Operation

When sending data to the printer each character is inspected and then sent if needed. A column count is kept to determine the position of the printer’s print head which is compared to the selected column width of the paper. If a space character is found, it is not sent right away to the printer. The following characters are checked and if no other character other than a space is present in the line, a CR LF or CR LF LF (Double spacing) is sent to the printer disregarding the received spaces.

The SNA host can send transparent data to the printer. Most of the time this EBCDIC data is converted into ASCII because transparence is generated by the application (e.g. JES, POWER) which looks for a character less than an EBCDIC space (x’40’) in value, if this character is found, the print line is sent in transparent form. Usually the character causing this is a null (X’00’) inserted in a JOB name or ROOM number because no value was assigned. If the actual SNA data received from the host needs to be printed, the first two data characters must be a transparent indicator (TRN X ‘35’) followed by the number of transparent characters in hexadecimal. Example message received from SNA host:

TRN # TRN # data —> 1st TRN # generated by JES 2nd TRN # generated by program The printer can be connected to the A/S-4 in many ways as mentioned below:

1. Printer directly connected to the terminal port with a single cable. In this configuration no

VDU is present. The host must do an Auto-BIND to connect the A/S-4 to he application (e.g. JES2, CICS) or use the Auto Logon function of the unit. With a single device, only one LU is needed but both may be used. Normally the VDU LU is the LU used when running with a single LU. The host must start the print job since no VDU is present. Hardware throttle (must have CTS before sending data) or software throttle (XON/OFF protocol) may be used to control the rate of data going to the printer.

2. Printer attached to a VDU’s auxiliary/printer port where the VDU is directly connected to the

terminal port of the A/S-4. This mode of operation allows the VDU to run at a faster baud rate than it’s attached printer. Having two LUs active, one for inbound (to host) data and an outbound (from host) LU will increase the speed of the printer and also allow the VDU to start or stop jobs, interrupt the printer or allow a card device to send a job in to the host while a job is being printed. Software or hardware throttle is supported.

3. Printer attached with the special “Y” VDU/Printer cable. The VDU and printer must run at

the same baud rate in this setup and hardware throttle is the only way to control the flow of data to the printer (XON/OFF not supported). When using the “Y” cable, the VDU will be able to receive data while the printer is off-line, replacing paper or throttling. This configuration is very similar to item 2 with two LUs active which allows the VDU to control the printer. In this mode the VDU (PC or computer) can go off-line and run applications while the printer is receiving data from the SNA host, as long as the VDU supplies Data Terminal Ready (DTR) pin 20 to the A/S-4.

PROTOCOL CONVERTER MODEL A/S-4

8.4 Batch Default Options

The A/S-4 has the capability of loading all it’s Batch options from the VDU (computer) without going through any menus. This is done by receiving the shift out (X’0E;) character followed by the options selected in hexadecimal form. The VDU and A/S-4 must be set to receive and transmit an 8-data bit word with no parity, so all 8 bits of the hexadecimal characters are received. Once all the new Batch default options are loaded, the A/S-4 is then automatically set to run in the Batch 3776/77 mode. Below is the Batch options with its bit location.

CHAPTER 9: Battery RAM

9. Battery RAM

All operating parameters selected from the configuration menus are saved in battery backed-up RAM (Random Access Memory). Therefore, if AC power to the A/S-4 is interrupted, it is unnecessary to reenter the parameters previously selected. If the unit is powered off for seven days or more, the parameters will probably be lost.

PROTOCOL CONVERTER MODEL A/S-4

10. Maintenance

The A/S-4 is designed to perform all of its tasks with maintenance free operation. You may prolong the life of the unit by cleaning any dust build-up in the unit. Dust may be removed by blowing and/or brushing with a long bristle paint brush.

1. Check to see if the power indicator light is ON: Make sure the unit is plugged in.

2. Check for loose cables and reconnect with retaining screws.

3. Check equipment connected to A/S-4; Modems, CPU, Terminals, and etc. for proper operation.

4. Restart unit after the above has been checked by unplugging A/S-4 and plugging it back in again. Now check for proper operation.

CHAPTER 11: Software Upgrade and EPROM Replacement

11. Software Upgrade and EPROM Replacement

Each EPROM has a label affixed to the top containing an address and the current data of the software in the IC. To replace the old EPROM with the new EPROM, follow the procedure below:

1. Unplug the A/S-4 and remove the cover by removing the 4 cover screws on the side and lifting the cover upwards.

2. Find the old EPROM on the electronic board. It is the only chip with a label affixed to it.

3. Note the little notch at the end of the EPROM is toward the front of the box. The new EPROMs, when inserted, must also have the notch toward the front of the box.

4. Remove the EPROM by taking a flat head screwdriver a pocket knife, or another flat edged instrument and inserting the flat edge between the ERPOM and the socket holding the EPROM at the two ends where there are no metal legs. Pry one end up just a little and then pry the other end up just a little. Continue prying both ends up just a little in a rocking back and forth motion until the EPROM becomes free of the socket.

5. Insert the new EPROM by aligning one row of metal legs first with one side of the socket. Make sure this row is firmly in the socket but not pushed down in the socket. Now align the other row of legs in the socket pushing the legs firmly in place but not down in the socket. Now if all legs are aligned, push the EPROM into the socket slowly watching to see if any legs bend. If any leg starts to bend or does bend, remove the EPROM as in Step 4 above and straighten the leg as much as possible by hand or with pliers, if available. Try inserting the EPROM again. If a leg continues to bend or breaks off, do not throw the EPROM away, return it to the factory.

6. With cover still off, turn the box on and check for the power up attribute message on the terminal device. If the power up message is displayed continue to step 8.

7. If not, check for any bent legs or any leg that did not go into the socket. Also make sure the EPROM notch is toward the front of the box. Correct any EPROM problems found. If the EPROMs cannot be made to work (display the attribute message), return the A/S-4 and EPROMs to the address on the title page for repair. Please call for a Return Authorization Number.

8. Replace the cover of the A/S-4 and insert and tighten the 4 cover screws.

Appendix A: 3274 SNA

Communication Operations

This appendix is intended to give a VDU operator the basic description of the System Network Architecture (SNA) for a 3278 CRT (or like device) in the area of remote communications.

First the 3278 CRT is connected to a 3274 controller that allows 32 3278 CRT’s to communicate to an IBM mainframe computer. SNA calls the 3274 controller a PU (physical unit) and the 3278 CRT a LU (logical unit).

Communications with the host computer and the CRT basically follow the following steps.

1. The line is activated - This means a phone line is established between the host computer and the 3274 controller. This maybe done by dialing a phone for dialup applications or having a host computer operator connect a leased phone line.

2. The PU is activated - The host sends the first message down the phone line to the 3274 controller (PU) to tell it to start communications. The 3274 controller then tells the host when it is ready to start.

3. The LUs are activated - The host now tells all the 3278 CRTs (LUs) to start communications. The CRTs then tell the host when they are ready to start.

4. SSCP (System Services Control Point) sends a message to the LU - The CRT at this point receives an enter request logon message from SSCP if the host system is GENed to send a SSCP message. A GEN is how the host system operators set up different CRT options. At this point the CRT is considered to be in a SSCP to LU session. Session means that two devices are talking with each other.

5. The CRT operator may now enter a request logon message for an application - This allows the operator to request a logon to different applications like CICs, IMS or TSO on any available system. (example; Test System A or B or a Production System). If the CRT will always be assigned to one application, the host system may be GENed (optioned) to automatically request an application logon, in which case this setup does not need to be performed by the VDU operator.

6. The system now BINDs the CRT to the application - This establishes communication between the CRT and the application. The 3274 controller will usually clear the CRT screen when this happens. The CRT is now considered to be in a LU to LU session.

7. The application sends a welcome or signon application message to the CRT - This now allows the operator to run his application or transactions. While communicating with the application, it is usually on a demand-response basis. The operator enters data or answers a question and the host sends back the information or more questions. This proceeds until the operator has completed the assignment.

APPENDIX A: 3274 SNA Communication Operations

NOTE

Some applications may not send a welcome message. The operator must send the first message to start the transactions.

8. After the operator has finished working, he should signoff the application. The system will then UNBIND the CRT so that the CRT and applications are no longer communicating with each other. This leaves the CRT available for an operator to logon to another application. The 3274 controller will usually clear the CRT when this happens. SSCP will then send an enter request logon message which puts the CRT back to step 4 so as to start things over again.

Appendix B: General 3770 SNA

Communication Operations

This appendix is intended to give a basic description of the System Network Architecture (SNA) operation for an IBM 3776/77 Model 3 and 4 multiple logical unit (MLU) work station in the area of remote communications.

The 3776/77 Model 3 and 4 is a stand alone work station consisting of; 1) console with keyboard and display. 2) console-mounted line printer with optional card reader and line printer. SNA calls the controller port a PU (Physical Unit) and the attached printers, consoles, card readers and disk LUs (Logical Unit).

Communications with the host computer and the work station basically follows the following steps.

1. The line is activated - This means a phone line is established between the host computer and the work station. This maybe done by dialing a phone for dialup applications or having a host computer operator connect a leased phone line.

2. The PU is activated - The host sends the first message down the phone line to the 3776/77 work station’s controller (PU) to tell it to start communications. The work station then tells the host when it is ready to start.

3. The LUs are activated - The host now tells all the attached devices (LUs) to start communications. The devices respond to host when they are ready to start.

4. SSCP (System Services Control Point) may send a message to the console requesting a logon message for the active LUs if the host system is GENed to send a SSCP message. A GEN is how the host system operators set up different work station options. At this point the console is considered to be in a SSCP to LU session. Session means that two devices are talking with each other.

5. The work station operator may now enter a request logon message for an application - This allows the operator to request a logon to different applications like JES2, POWER or CICs on any available system. For example; Test System A or B or a Production System. If the work station will always be assigned to one application, the host system may be GENed (optioned) to automatically request an application logon, in which case this setup does not need to be performed by the work station operator.

6. After a good logon message is received by the host it will BIND the requested LUs to the application - This establishes communication between the work station and the application. The devices (console, printer, readers, disk) are now considered to be in a LU-to-LU session.

7. The application usually sends an active session message to the console - This allows the operator to run his application or transactions. At this time the operator can down-line load a job to the host, receive a job from the host, receive print, ask for status of jobs running on the system and many other operations.

APPENDIX B: General 3770 SNA Communication Operations

8. After the operator has finished working, he should signoff the application. The system will UNBIND all the LUs from the host system so that the work station and application are no longer communicating with each other. This leaves the work station available for an operator to logon to another application. SSCP may send an enter request logon message which puts the work station back to step 4 so as to start things over again.

Batch Terms:

Function Management Header 1 (FMH-1) is used to select a destination within an LU. When sent by the A/S-4 it indicates to the host which device (card reader or console) is sending data to the host, used in the same way when host sends FMH-1 to the A/S-4.

Function Management Header 2 (FMH-2) specifies the data management activities to be performed at the destination selected with the FMH-1. Typical data management activities are adding and replacing records, numbers of copies to print and date data created.

Appendix C: Conversion Charts

The following pages contain the EBCDIC-to-ASCII Character conversion chart. Characters under the “RECV” heading are the EBCDIC characters received from the SNA host. The ASCII equivalent is to the right under the “CONV” column. When EBCDIC data is directed to the printer the characters will be changed as described under the “PRT CONV” column.

The following notes are used to clarify the charts.

1. New Line - Send carriage return line feed (CRLF) to VDU.

2. Vertical Channel Select - Sends one line feed to printer and throws away next character.

3. Horizontal Tab - Positions print head by using spaces to correct column to page if tabs setup by SHF command.

4. Vertical Tab - Positions page by using CRLFs to correct line if tabs setup by SVF command.

5. Form Feed - Sends form feed character, or number of CRLFs if option set to position paper to top of page.

6. Throws away this character and two following if printer selected for a LU Type 3 running in Interactive mode(cursor positioning).

7. Sends CRLF to printer, checking for bottom of page and if so, positions paper to top of form by using additional CRLFs or sending a form feed.

8.Sends Backspace to printer if printhead positioned to column 2 or greater.

9. Sends LF to printer, checking for bottom of page and if so, positions paper to top of form by using CRLFs or the form feed character.

10. Indicates start of SNA character string (SCS), characters following will be handled as

described in Section 8.3 (SHF, SVF, SLD and VCS command).

11. Throw away this character and next one indicating number of transparent characters,

following data will not be converted to ASCII.

THW = Throw Away Character
