IPC-1600 Architecture

The architecture of the IPC-1600 provides many useful and powerful

multiuser capabilities under the UNIX system. Furthermore, single-user

applications using the IPC-1600 for general-purpose I/O, as well as for industrial control, can be done under MS-DOS.

IPC-1600 features include the following:

■

One 80C186 16-bit microprocessor (12.5 MHz).

■

Industry Standard Architecture (ISA) bus connectors (any 16- or 32-bit slot can be used).

■

One host Interrupt ReQuest (IRQ) level can be shared per 16 ports or one IRQ level can be assigned for all IPC-1600s (maximum of 7 boards

[112 ports]).

■

A 64-KB dual-ported Static Random Access Memory (SRAM) is used for data storage and buffering. This SRAM provides communications and control between the host processor and the IPC-1600 microprocessor. The host processor address range for this space is on 64KB boundaries and is switch selectable. This SRAM is “zero-wait-state” to the IPC-1600 microprocessor.

■

A 16KB RAM for local programs.

■

The use of a 16-bit data transfer on the Industry Standard Architecture (ISA) bus for maximum efficiency.

Chapter 6, “System Features,” provides more detailed information.

OVERVIEW 1-5

Ports and Drivers

The software that takes care of the I/O tasks between the user terminals/MODEMs/printers and the UNIX system is built into the IPC-1600 firmware to increase the UNIX system performance. End users get the benefit

of immediate keyboard/screen response and the enhancement of the overall performance of the UNIX system. The UNIX system driver supports the 8-bit character set.

The MS-DOS device driver supports an 8-bit character set and the

MS-DOS level interface.

Requirement:

If you plan to use both the native (boot) MS-DOS and the UNIX system

for the operation of the IPC-1600, proceed as follows.

Follow Chapter 3, “UNIX System Device Driver Installation,”

procedures with the following recommendations.

Install the IPC-1600 board(s) using controller memory address

❑

space below 1MB.

❑

Configure multiple IPC-1600 boards to share one Interrupt ReQuest (IRQ) level and share the same 64-KB controller memory address space.

The host computer must be set up to have base memory above 512KB (512KB to 640KB) disabled for the IPC-1600 to use controller memory starting addresses 080000h or 090000h. Refer to the customer documentation that came with your AT&T Work Group System (WGS) for information on how to disable base memory.

After installing hardware (Chapter 4), install MS-DOS software starting with Step 3 in Chapter 2. Be sure to specify same controller memory starting address and I/O address(es) that were set when installing the UNIX system device driver and IPC-1600 hardware.

MS-DOS Under Simul-Task and UNIX System

Operation

If you plan to use MS-DOS under Simul-Task 386 or to use only the

UNIX system for the operation of the IPC-1600, skip Chapter 2. Start with Chapter 3, “UNIX System Device Driver Installation,” and follow the

instructions for the installation of the software. Then install the IPC-1600 board per Chapter 4, “Hardware Installation.”

Native MS-DOS Operation

If you plan to use only native MS-DOS for the operation of the IPC-1600s, start with Chapter 2, “MS-DOS Device Driver Installation,” and follow the instructions for the installation of the software and hardware. Skip Chapter 3.

1-10 IPC-1600 USER’S GUIDE

Chapter 2: MS-DOS Device Driver Installation

Introduction

Comment:

This chapter provides instructions on how to install the MS-DOS device driver and diagnostics, which are on the diskette labeled “Intelligent Ports

Card (IPC-1600) MS-DOS Device Drivers and Diagnostics, Version 1.0.” Refer to Chapter 6, “System Features,” for information about the software support offered through the MS-DOS device driver.

Note:

The Intelligent Ports Card MS-DOS device driver supports the MS-DOS level interfaces in such a way that virtually any software application can access all serial I/O ports provided by the IPC-1600.

The same software is supplied on both a 5.25-inch diskette and a 3.5-inch diskette.

If you are using only the UNIX system for Intelligent Ports Card operation, you can skip this chapter and go to Chapter 3, “UNIX System Device Driver Installation.” If you plan to use MS-DOS under Simul-Task 386, follow the procedures in Chapter 3. The instructions in this chapter apply only to native MS-DOS. See the section, “IPC-1600 Diagnostics,” in Chapter 7 for diagnostics information.

Requirement 1:

Requirement 2:

The IPC-1600 board(s) must be installed and the I/O address, starting controller memory address, and IRQ level initially set before executing the

IPC16CNF program.

Each board in the system must be assigned an I/O address and the same starting controller memory address. The hardware Interrupt ReQuest (IRQ) level switches are all set to OFF unless the UNIX system is also being used to operate the board, in which case the UNIX system switch setup takes precedence. If you assign different controller memory addresses to IPC-1600s, only one board at a time can be used under native MS-DOS.

MS-DOS DEVICE DRIVER INSTALLATION 2-1

Installation Procedure

The following steps define the sequence of events for installing the

IPC-1600 for use in the native MS-DOS environment. Read the entire

procedure and supporting paragraphs before doing the installation. Write

down the hardware parameter settings for each board to be installed as you read through the procedure the first time. Then refer to these notes when you do the procedure.

Step 1:

Step 2:

Step 3:

Step 4:

Step 5:

Step 6:

Step 7:

Preconfigure the IPC-1600 boards by setting the DIP switches for a unique I/O address, a starting controller memory address, and IRQ level.

Install the hardware (IPC-1600 boards) using the instructions in Chapter 4, “Hardware Installation.”

Power up the system and load the files on the “Intelligent Ports Card (IPC-1600) MS-DOS Device Drivers and Diagnostics, Version 1.0” diskette.

Create or edit the CONFIG.SYS file using an editor such as EDLIN to include the DEVICE=\IPC\IPC16DOS.SYS entry.

Execute the IPC16CNF program to configure the IPC-1600 and

configure the driver. Reconfigure the IPC-1600 DIP switches if necessary to match the

software assignments. Reboot the machine to install the driver.

The following paragraphs provide more information for each of the installation steps. Note that Steps 5 through 7 can be executed when necessary to reconfigure the driver and/or port characteristics.

2-2 IPC-1600 USER’S GUIDE

Installation Procedure

Preconfigure the IPC-1600 Boards

Set the starting controller memory address (DS1, SW8—1), the I/O

address (DS1, SW11—9), and the IRQ level (DS2, SW8—1) for each IPC-1600 to be installed. Note that IRQ levels are not used by the MS-DOS driver.

Therefore all DS2 switches should be set to the OFF position (Note 2). Refer to Appendix A, “Hardware Parameter Settings,” for switch location and

decode information.

The following table identifies the initial options. The driver default

addresses are shown in bold type face.

The IPC-1600 (16-bit transfer board) cannot share a 128-KB memory address space with 8-bit transfer boards like a hard disk controller board or a video display board.

MS-DOS DEVICE DRIVER INSTALLATION 2-3

Installation Procedure

Install the Hardware

Refer to Chapter 4, “Hardware Installation,” and follow the instructions for the installation of the board. Ignore any instructions in Chapter 4 involving the DS1 and DS2 DIP switches, since they have already been done in this procedure.

Load the Software

Power up the system [AT&T Work Group System (WGC) computer] to boot native MS-DOS (Version 3.0 or later) from either the floppy diskette or the system disk drive.

Insert the MS-DOS device driver diskette into the appropriate diskette

drive and close the diskette drive door.

Use the MS-DOS COPY command to copy all files from the diskette to the system disk. It is recommended that you create a separate directory for the IPC-1600 files as shown in the following examples. Note that system

prompts are machine dependent.

As shown in the following screen display, first, shift from the “A” drive to

the “C” (system disk) drive and create a directory named IPC as follows.

$ C:

$ mkdir ipc

2-4 IPC-1600 USER’S GUIDE

Installation Procedure

Now, change directory (cd) to IPC and copy the files on the diskette in the

“A” drive or in the “B” drive to the system disk drive as follows. The

example uses the “A” diskette drive; the system disk is the “C” drive.

Change directory to an optional separate directory to contain the IPC-1600 software.

C: $ cd ipc

Copy the files from the “A” drive to the “C” drive

C:\IPC $ copy a:*.* /v A:IPC16CNF.EXE A:IPC16DOS.SYS A:IPC16DIA.COM

3 File(s) copied

C:\IPC $

Remove the “Intelligent Ports Card (IPC-1600) MS-DOS Device Drivers

and Dagnostics, Version 1.0” diskette from the diskette drive and properly

store the diskette.

There are two files on the “Intelligent Ports Card (IPC-1600) MS-DOS Device Drivers and Diagnostics, Version 1.0” diskette concerned with the installation of the MS-DOS driver:

IPC16CNF.EXE

Use this command to configure the Intelligent Ports Card driver characteristics.

IPC16DOS.SYS

Selecting INT 14 support deactivates the DOS capability of assigning and using names for the installed communications ports. This allows the channels to be accessed only through INT 14h calls. If DOS support is not desired, selecting this option decreases the size of the driver.

The following screen display shows how to select these options.

Installation Procedure

Finishing Up

Quitting the IPC16CNF program using the Q)uit option produces various

messages depending on what has been done before the exit request. During

the exit process, a combination of the following prompts can be displayed.

Re-Configure the IPC1600(s) (Y/*) :

Responding “Y” to this prompt causes the IPC-1600 to be reprogrammed. The system can then be used without a reboot.

However, on the next reboot, the system will revert to the previous configuration unless the changes are saved to the system disk.

Save Changes to Disk for Re-Boot? (Y/*) :

Responding “Y” to this prompt changes the IPC16DOS.SYS file on the system disk to reflect the new configuration data. The new

configuration is installed by rebooting the system. If the previous

prompt was to “Re-Configure the IPC1600(s)” and the response was

“Y”, the changes are currently in effect. However, on the next reboot, the system will revert to the previous configuration unless the changes are saved to the system disk.

Quit? (Q/*) :

Responding “Q” to this prompt terminates the program returns to MS-DOS.

The following screen display shows the typical prompts after changing the

IPC-1600 configuration options and quitting for the initial installation.

MS-DOS DEVICE DRIVER INSTALLATION 2-13

Installation Procedure

Reconfigure the Boards If Necessary

Requirement: Be sure to take notes throughout this phase of

installation. Write down I/O addresses and the memory addresses so that once the device drivers have been installed you will have a permanent record to which you may later refer. Likewise, if you are going to remove or add a board, write down any changes that you make in the process. A sample configuration record is shown in Appendix A.

Refer to Appendix A, “Hardware Parameter Settings,” for switch location

and decode information if it is necessary to change these settings to match the software (driver) configuration established by the IPC16CNF program. Note that Steps 5 through 7 (this discussion is Step 6) can be executed when necessary to reconfigure the driver and/or port characteristics. The following

screen display shows the typical prompts associated with reconfiguration.

Removing the MS-DOS Device Driver

To remove the Intelligent Ports Card MS-DOS device driver from the

system, use an editor, such as EDLIN, to delete the entry in the CONFIG.SYS file which corresponds to DEVICE=\IPC\IPC16DOC.SYS. Then reboot

the system.

If you want to free the system disk space occupied by the IPC-1600

software, delete files along with the IPC directory (RMDIR). Note, you may want to keep the

IPC16DIA program if you expect to run diagnostics from the system disk.

The following screen display shows how to delete (DEL) all files under

MS-DOS DEVICE DRIVER INSTALLATION 2-17

Limitations of the IPC-1600 MS-DOS

Device Driver

All IPC-1600 boards in the system must be assigned the same starting controller memory address; otherwise, only one board can be accessed under native MS-DOS. All IPC-1600s can be diagnosed regardless of controller

memory address assignments; however, the controller memory address switch settings must be below 1MB.

This MS-DOS device driver will NOT drive the following:

■ Any indigenous serial I/O ports such as COM1: and COM2:.

■ The indigenous parallel printer ports LPT1: and LPT2:.

The built-in MS-DOS RS-232C and printer device drivers can coexist with the Intelligent Ports Card MS-DOS device driver to provide services on the indigenous ports.

Any application software that bypasses all MS-DOS device drivers and controls the hardware directly will NOT work with an Intelligent Ports Card and its MS-DOS device driver. However, those applications which bypass the high-level MS-DOS interfaces and use INT 14 interfaces will work.

In the native MS-DOS environment, the recommended

machine-to-machine file transfer command is as follows:

COPY filename /B COM

x /B

such that the entire file is transferred including the execution of the CTRL Z keystroke sequence.

Chapter 3: UNIX System Device Driver

Installation

Introduction

Comment:

This chapter provides instructions for installing the IPC-1600 UNIX system device driver, which is on the diskette labeled “Intelligent Ports Card (IPC-1600) UNIX System V/386 Device Drivers, Version 1.0.” This chapter also provides software-related information about removing a board and installing additional boards.

Note:

It is strongly recommended that you install the device driver before you

install the hardware.

Requirement 1:

The same software is provided on both a 5.25-inch diskette and a 3.5-inch diskette.

If you are using only native MS-DOS for IPC-1600 operation, you can skip this chapter. Chapter 2, “MS-DOS Device Driver Installation,” provides MS-DOS driver installation and setup instructions. If you intend to run MS-DOS under Simul-Task 386, use the installation instruction in this chapter.

Certain system tunable parameters should be adjusted to obtain proper system performance. Also, sufficient system memory must be

available to support the number of boards being installed. Refer to the “Tunable Parameters and Memory Requirements” section of this chapter for more information. It is recommended that the tunable parameters be adjusted before installing the IPC-1600 UNIX system software to avoid having to do a separate idbuild process.

Requirement 2:

Be sure to take notes throughout this phase of installation. Write down the Interrupt ReQuest (IRQ) assignment(s), I/O address(es), and the controller memory address(es) so that once the device driver has been installed you will have a permanent record to which you may refer when you install the hardware. Likewise, if you are going to remove or add a board, write down any changes that you make in the process. A sample configuration record is shown in Appendix A.

The installation of the IPC-1600 UNIX system driver and related software is independent of these requirements. However, to obtain proper system performance, these parameters should be adjusted before the installation of the IPC-1600. Refer to the UNIX System V/ 386 Operations/System

Administration Guide for additional information and procedures on setting tunable parameters. By adjusting these parameters and then installing the

IPC-1600 UNIX system software, only one system reboot is necessary to

install both the new tunable parameter data and the IPC-1600 data.

Failure to adjust these parameters may result in table overflow warning

messages and poor performance.

General Installation Procedures

Power up the AT&T WGS computer, making sure that no diskette is in the diskette drive(s) during the boot phase. Wait until the UNIX system is ready, and then log in using either “root” or the privileged access user administration login you have been assigned.

Insert the “Intelligent Ports Card (IPC-1600) UNIX System V/386 Device

Drivers, Version 1.0” diskette into the appropriate diskette drive (5.25-inch or

3.5-inch drive) and close the diskette drive door. At the UNIX system prompt, enter the following:

installpkg

Press the ENTER key. This invokes the UNIX system software package

installation program, which allows you to install the IPC-1600 UNIX system serial I/O driver.

More information about using the installpkg command is given in the

UNIX System V/386 Operations/System Administration Guide.

Note 1: Each IPC-1600 board in the system must be assigned a

unique I/O address, a controller memory address range, and a hardware Interrupt ReQuest (IRQ) level which do not conflict with any other board types in the system. All IPC-1600 boards in a system must be set up to support ONE of the following conditions:

Share controller memory and share one IRQ level (preferred condition)

Share controller memory and have unique IRQ

levels

Unique controller memory address assignments and share one IRQ level

Unique controller memory address assignments and unique IRQ levels.

Note 2:

3-4 IPC-1600 USER’S GUIDE

The use of 080000h or 090000h as the controller memory starting address requires that the base memory above 512KB (512KB to 640KB) be disabled.

To remove all IPC-1600 board information from the kernel, log in as

“root” and execute removepkg. When prompted, select the “IPC-1600, Intelligent Ports Card — Version 1.0” item.

Changing IPC-1600 Configuration

You can reinstall the driver on top of the current driver when you need to

add or change the IPC-1600 configuration information. To change the existing configuration of IPC-1600 board(s), reinstall the “Intelligent Ports Card (IPC-1600) UNIX System V/386 Device Drivers, Version 1.0” software

package (installpkg). Specify the proper number of boards and then assign

the appropriate interrupt request level, I/O address, and starting memory controller address for each board.

Following shutdown, power down the system and set the DIP switches on

the IPC-1600 to match the information specified to the device driver. The new configuration will be installed when the system is powered up.

Chapter 4: Hardware Installation

Introduction

The IPC-1600 board can be installed in any 16-bit or 32-bit bus expansion

slot in following machines:

■ AT&T 6386E Work Group System

■ AT&T 6386/25 Work Group System

■ AT&T 6386E/33 Work Group System

■ AT&T 6386E/33 Work Group System Model S.

Refer to the appropriate “User's Guide” supplied with your machine for board installation instructions. This chapter guides you through the process of installing the appropriate hardware. However, refer to the documentation that came with your system for instructions on how to install/remove a bus expansion slot board.

Also, be sure to refer to the notes you were instructed to make when you

were installing the software (Chapters 2 and 3). You will need these notes to

set the various switch settings on the IPC-1600 board.

Although this chapter does not explicitly cover removing a board or installing an additional board or boards at a later time, the instructions provided here can help you do future hardware changes.

Note:

Each IPC-1600 board in the system must be assigned a unique I/O address, a controller memory address range, and a hardware Interrupt ReQuest (IRQ) level which do not conflict with any other board types in the system. All IPC-1600 boards in a system must be set up to support ONE of the following conditions:

Share controller memory and share one IRQ level (preferred condition)

Share controller memory and have unique IRQ levels

2. Unique controller memory address assignments and

share one IRQ level

Unique controller memory address assignments and

unique IRQ levels.

HARDWARE INSTALLATION 4-1

Preparation

Prepare Machine for Installation

If the machine is powered-up and is running the UNIX operating system,

use the shutdown command to bring down the operating system as shown in the following screen display.

# cd / # shutdown

Set the power switch of the system and of all external devices to “OFF.” Unplug the system module power cord. Using the documentation that came with your machine, prepare an

expansion bus slot for the installation of a board. This will typically require the removal of a cover and a board slot filler plate.

4-2 IPC-1600 USER’S GUIDE

Preparation

Prepare the IPC-1600 for Installation

Set the Controller Memory Starting Address

Locate the DS1 Dual In-line Package (DIP) switch (a group of eleven

switches) on the IPC-1600. Refer to Appendix A, “Hardware Parameter

Settings,“ for switch location information and instructions on how to set the

controller memory starting address (DS1, SW8 through SW1) to correspond to the values established when installing the software (Chapters 2 and 3).

Set the Input/Output Port Address

Next, locate the DS1 DIP switch. Set the selected I/O port address (DS1, SW11 through SW9). For switch location information and instructions on how to set the selected I/O starting address, refer to Appendix A. Set the I/O port address switches to correspond with the values specified when installing the software (Chapter 2 and 3).

If you are adding more than one board, make sure that the selected I/O starting addresses you are now specifying do not conflict.

Set the Interrupt Request Level

Locate the DS2 DIP switch. Follow the instructions in Appendix A for setting the IRQ level. Again, each IPC-1600 board that you install can have its own IRQ level or one IRQ can be used for all IPC-1600 boards. Set the IRQ switches to correspond to the IRQ level specified when installing the software (Chapters 2 and 3).

HARDWARE INSTALLATION 4-3

Connect the 16-Ports Fanout Module

Cables

After setting the I/O port address, the controller memory starting address, and the hardware interrupt request level for the board, you are ready to connect the ribbon cables and port modular cables to the 16-Ports Fanout module as follows.

If you have the optional AT&T IPC-1600 Ports Cabinet, locate and install

the cabinet now. Refer to Appendix C, “AT&T IPC-1600 Ports Cabinet,” and the documentation that came with the cabinet for installation information. After installing the cabinet, return to this procedure to “Connect the Ribbon Cables to the IPC-1600” and “Install the Board” in the host computer.

If you DO NOT have the optional AT&T IPC-1600 Ports Cabinet, locate

the two 80-conductor ribbon cables and the 16-Ports Fanout module. Connect the ribbon cables to the 80-pin connectors at the rear of the 16-Ports Fanout module. The connectors on the ribbon cables are keyed for proper alignment with the connectors at the rear of the fanout module. Make sure that the retaining clips are properly secured.

If you DO NOT have the optional AT&T IPC-1600 Ports Cabinet, connect

the port modular cables to the 16-Ports Fanout module. When connecting the

modular cables to the 16-Ports Fanout module, it is important to label (identify) the circuit(s). The label information should include the port

identification (tty

IPC-1600

Route the ribbon cables from the 16-Ports Fanout module to the host computer. Thread the ends of the ribbon cables through the board slot opening in the host computer and connect them to the IPC-1600 board. The connectors are keyed for proper alignment with the 80-pin headers on the board. Observe the port markings on the front of the 16-Ports Fanout module to insure correct port numbering on the fanout module. Connect the ribbon cable for ports 9 through 16 to header P3. Connect the ribbon cable for ports 1 through 8 to header P4. Refer to Appendix B, “Serial Input/Output Device Interface,” for more information on these connections. Make sure that the retaining clips are properly secured.

HARDWARE INSTALLATION 4-5

Install the Board

Follow the instructions in the documentation that came with your machine

for installing a board.

Carefully pass the excess ribbon cable through the board slot opening

until the board can be plugged into the 16- or 32-bit Industry Standard Architecture (ISA) bus connector. Align the IPC-1600 board with the selected board slot and plug the board into the corresponding connector.

Secure the IPC-1600 board with the mounting bracket using the 2.25-inch long-shank screws. Then secure the bracket to the chassis with the screw previously used for the filler plate.

After the entire IPC-1600 system has been installed, check that all mechanical connections have been tightened before putting the system back together and applying power to the system. Make sure that all cables have

been neatly routed and do not pose a hazard to personnel.

■

The serial I/O ports can be mapped into the MS-DOS and UNIX system environments to provide a total of 64 ports (four IPC-1600 boards). When one IRQ level is shared among seven IPC-1600 boards, 112 ports can be supported.

The IPC-1600 base memory address and I/O base address are both

configurable via on-board DIP switches.

One IRQ line can be assigned for each IPC-1600 or shared among all equipped IPC-1600s out of a total possible eight interrupts (IRQ3—IRQ5, IRQ7, IRQ10—IRQ12, and IRQ15). A maximum of seven boards can be

equipped when one IRQ is shared among all IPC-1600s. A maximum of four board can be equipped when one IRQ is assigned per board.

Eight 8530 serial communications controllers function as dual-channel, Universal Asynchronous Receiver-Transmitters (DUARTs) to provide a total of sixteen RS-232C channels (ports) complete with the following features:

■

The performance of the IPC-1600 expressed in terms of line occupancy at a prescribed baud rate in the raw and cooked modes with no flow control is as follows. In the cooked mode, canonical processing is enabled. In the raw mode, canonical processing is disabled. The line occupancy formula is:

Line Occupancy (%) =

Note:

The input capacity of the IPC-1600 is determined by the number of lines (ports) simultaneously operating at 100% occupancy with no flow control as

follows.

The line occupancy formula may have results greater than

100%. This is reserve capacity that is NOT achievable. The following line occupancy results are typical of an AT&T 6386E/33 WGS Model S with one IPC-1600 board.

Performance Characteristics

The output capacity of the IPC-1600 is determined by the number of lines

(ports) simultaneously operating at 98% occupancy with no flow control as

follows.

Raw Mode:

16 ports at 4,800 bps 16 ports at 9,600 bps 14 ports at 19,200 bps

7 ports at 38,400 bps

Cooked Mode:

16 ports at 4,800 bps 16 ports at 9,600 bps 14 ports at 19,200 bps

7 ports at 38,400 bps

Operating beyond these input limits with no flow control will result in

loss of characters. Operating beyond these input limits WITH flow control

will result in decreased line occupancy and no data loss. No data loss is associated with output regardless of flow control; however, reduced occupancy will result if these limits are exceeded.

IPC-1600 Diagnostics

IPC-1600 Test Descriptions

Host 64KB Dual-Ported Memory Tests

The host processor dual-ported memory test diagnostics execute in the

host processor. These tests write to memory, read the memory, and compare

what is read to what was written. The IPC-1600 is held reset and the dual-ported memory is enabled during test execution.

Host/lPC-1600 Interface Tests

The host processor/IPC-1600 interface tests execute in both the host processor and the IPC-1600. The IPC-1600 is reset and the BIOS is downloaded and executed. The host processor sends a Non-Maskable Interrupt (NMI) to the IPC-1600 and the IPC-1600 responds with an IRQ to acknowledge the NMI. The test passes if the interrupt communication is

successful in both directions.

IPC-1600 64K Dual-Ported Memory Tests

The dual-ported memory tests execute in both the host processor and the IPC-1600. The IPC-1600 is reset and the BIOS is downloaded and executed. The host processor downloads the diagnostic and transfers control from the BIOS to the test routine. The diagnostic executive in the host processor monitors the test results.

IPC-1600 16K Local Memory Tests

The 16KB local memory tests execute in both the host processor and the IPC-1600. The IPC-1600 is reset and the BIOS is downloaded and executed. The host processor then downloads the diagnostic tests and transfers control from the BIOS to the test routine. The IPC-1600 executes the tests and the

diagnostic executive in the host processor monitors the test results.

IPC-1600 FEPOS Integrity Tests

The Front End Processor Operating System (FEPOS) integrity tests execute in both the host processor and the IPC-1600. The IPC-1600 is reset, the BIOS is downloaded and executed, and the FEPOS is downloaded and executed. The diagnostic executive in the host processor monitors the FEP operating

system for test results.

IPC-1600 Communication Ports Tests

The communication ports tests execute in both the host processor and the IPC-1600. These tests use the IPC-1600 FEPOS to exercise each port on the IPC-1600.

A combination of four baud rate (1200, 9600, 19200, and 38400 bps), four data word sizes (5, 6, 7, and 8 bits), two stop bits (1 and 2), and three parity selections (none, odd, and even) are used to test each port. Each port is programmed to an internal loopback mode; therefore, external loop around cables are not needed. However, note that the transmit data is available at the port for external use while in the loopback mode. Any test data appearing on

a terminal connected to a port under test should be ignored since the communication ports diagnostics are internal, standalone tests.

Helpful Hints

Typically, the lower interrupts on the Industry Standard Architecture (ISA) bus are used by other circuit boards in the system. Therefore, to prevent configuration conflicts, try using some of the higher interrupts (IRQ 10, IRQ 11, and IRQ 15) for the Intelligent Ports Card.

Make sure that the Intelligent Ports Card is installed in a 16-bit or a 32-bit

ISA-compatible bus slot.

Make sure that the hardware for the Intelligent Ports Card correctly

corresponds to the software selections for the I/O address, starting controller

memory address, interrupt request level, and board type.

When possible, use the default settings during the installation of the

Intelligent Ports Card.

Use shared IRQ level and controller memory starting address assignment

whenever possible.

Use controller memory address space below 1MB when possible. The use of controller memory address space below 1MB is required for native MS-DOS and diagnostics operation.

IPC-1600 boards may not work correctly if configured to share a 128KB controller memory address space with other boards types. This is because the IPC-1600 uses highly efficient 16-bit data transfers, and many other boards use less efficient 8-bit technology. The ISA bus architecture precludes mixing the two board types in the same 128KB address space.

Boards can be assigned controller memory address space above 1MB for UNIX system operation and reassigned to use supported address space for the

purpose of diagnostics (by changing switch settings). Remember to reset the switches for UNIX system operation.

Some applications may be coded assuming input buffer overflow at 256

characters. The IPC-1600 uses 257 character input buffers.

If you are using an 8-conductor cable, make sure that the cable is straight

through. A 3B2 computer 8-conductor cable that provides cross-overs between the two modular ends will NOT work.

When using intelligent terminals (for example, AT&T 630 MTG) with

MS-DOS application programs through Simul-Task 386, make sure that all function keys are correctly set.

Helpful Hints

When using a Hayes* compatible MODEM, dial out once to configure the

MODEM before caIling into the MODEM.

The AT&T 446 Laser Printer and the HP† LaserJet Series II printer must

be installed on a serial port configured as a ttyih

xyy device under the UNIX

system.

Use stty clocal to prevent loss of printer data for printers which raise Data

Carrier Detect (DCD) to signal erroneous data. These printers include the AT&T 446 Laser Printer and the HP LaserJet Series II printer.

Use stty -clocal to allow UNIX system detection of printer disconnect.
