Introduction to DTC Manager/UX

This chapter describes the DTC Manager/UX software and the types of DTCs it can manage.

The DTC Manager/UX software provides management functions for Data Communications Terminal Controllers (DTCs) that enable you to create and maintain DTC conﬁguration ﬁles. The DTC Manager/UX runs on the HP 9000 Series 7001 and 800 computer systems.

The HP 9000 system is called the host system. DTC Manager/UX manages DTCs that are directly connected to the host system or connected to other HP 9000 systems on the same LAN.

Note Other HP software products are available for managing DTCs from a PC or from an

HP 3000 system.

DTC overview

The HP Data communications and Terminal Controller (DTC) is a versatile communications server for connecting systems to terminals, printers, and other asynchronous devices. The types of connections available through a DTC are determined by the connector cards or boards mounted in and conﬁgured for that DTC.

A DTC controls the transfer of data between the devices connected to it and the computer systems which those devices can access. The DTC controls communications that would otherwise need to be controlled by the computer system. Therefore, the DTC frees system resources and can improve the processing performance of the Hewlett-Packard computers that use the DTC as their communications controller.

1 Except Series 700 diskless systems

Page 16

DTC Manager/UX overview

As a LAN-based communications controller, each DTC can be located wherever it is most convenient for you. You may choose to locate DTCs close to the devices they control. Alternatively, you may locate them some distance away from the computer systems to which they provide access. The design of the DTC enables you to tailor your physical layout to your own needs.

The maximum number of ports available on a DTC depends on the DTC type and the combination of boards installed in it. Refer to the DTC hardware installation manuals for more detailed descriptions of the DTCs.

DTC Manager/UX overview

The DTC Manager/UX (also referred to as the DTC Manager) consists of a set of commands for conﬁguring and troubleshooting DTCs (except DTC 16RX, DTC 16iX, DTC 48/3000 and HP ARPA Telnet Express). The ﬁrmware of the DTC itself contains only the code for self-test, self-diagnostics, and download protocol. Therefore, most of the DTC's operational software must be loaded when the DTC is ﬁrst switched on through a process referred to as software download. The software code to be downloaded to each DTC resides permanently on the computer that is responsible for managing and controlling the operations of that DTC.

Page 17

DTC Manager/UX overview

DTC Manager/UX commands

Note All DTC Manager/UX commands require superuser privileges.

• dtcconfig configures, adds, deletes, and/or modifies the DTC, and produces the

configuration information that is later downloaded to the DTC

• dtclist lists DTC configurations or lists events in the event log

• dtcdiag reports DTC diagnostic information and has the following command

synonyms:

• dtcreset—resets a DTC, board, or port

• dtcupload—uploads a DTC, board, or port

• dtcdownload—downloads EEPROM code to a board

• dtcstat—obtains the status of a DTC

• dtctest—tests a CPU/LAN board or a selected port

• dtcconnstat—obtains the status from selected ports

• dtcquickswitch—switches DTC management from one host to another

• dtctraceon—turns on extended trace on selected ports

• dtctraceoff—turns off extended trace on selected ports

• dtcmodifyconfs modifies, owns/disowns, and exports/imports DTC

configurations and has the following command synonyms:

• dtcexport—exports a DTC configuration to a file

• dtcimport—imports a DTC configuration from a file

• dtcown—owns a DTC

• dtcdisown—disowns a DTC

• dtcping performs a ping operation on DTCs

• dtccheckip performs a check for duplicated IP addresses

Page 18

DTC Manager/UX overview

Required daemons

The following daemons must be running on the HP 9000 host computer for the conﬁguration information to be downloaded to the DTC.

Note These daemons must be run with superuser privileges.

• rbootd—remote boot server daemon

• dtcnmd—DTC network management daemon

• dtcnmp—DTC state machine daemon

The rbootd daemon waits for a boot request packet from the DTC. When it receives the packet, it downloads the code and the conﬁguration information that was generated using the dtcconﬁg command.

The dtcnmd daemon handles the transmission of network management data between the DTC management platform and the DTC.

The dtcnmp daemon executes the network management protocol enabling DTC requests to be sent and received between the DTC Manager/UX user interfaces (dtcconﬁg, dtcdiag and dtcmodifyconfs) and the DTC. The dtcnmp daemon is always started by dtcnmd.

If you need information on the dtcnmd, dtcnmp and rbootd daemons, refer to your man pages.

DTCs that can be managed by DTC Manager/UX

Five types of DTCs can be managed by the DTC Manager/UX:

DTC 16TN and DTC 16MX

The DTC 16TN has 16 asynchronous ports (separated in two eight-port groups) and does not support add-on boards. Each port group can be conﬁgured to be modem or direct-connect.

Note The full functionality of the DTC 16MX is only available using HP OpenView DTC

Manager. When managed by the DTC Manager/UX, the DTC 16MX is configured and functions exactly like a DTC 16TN. Therefore, only the DTC 16TN product is referred to in this manual.

Page 19

DTC Manager/UX overview

DTC 16

The DTC 16 can be ﬁtted with two boards of eight ports, giving a maximum of 16 ports. It can provide connections for up to 16 directly-connected devices, or 12 remote devices using modems, or a combination of both. The back of the DTC 16 actually has three slots; two slots for connector cards and one empty slot.

DTC 48

The DTC 48 can be ﬁtted with six boards of eight ports, giving a maximum of 48 ports. It can provide connections for up to 48 directly-connected devices, or 36 remote devices using modems, or a combination of both.

The back of the DTC 48 contains six slots, each of which can contain one of the available connector boards. The slots are numbered 0 through 5 (from bottom to top). When connector boards are mounted in the slots, they are often referred to by their slot locations: for example, the board contained in slot 1 becomes board 1.

Note DTC 48s with a date code less than 3110 require a memory extension and must be

upgraded with the DTC 48 Upgrade Kit (HP product 2348A). DTC 48s with a date code of 3110 or later and DTC 16s do not require a hardware memory extension.

DTC 72MX

The DTC 72MX can be ﬁtted with three boards of 24 ports, giving a maximum of 72 ports. The DTC 72 can provide connections for up to 72 directly-connected devices, or remote devices using modems, or a combination of both.

On the back, there are four slots. You must have a LAN board installed in one of the slots. Slot 0 is usually used for the LAN card. The other three slots can take boards which provide connections for up to 24 devices each.

The DTC 72MX has three port groups per board. Each port group has eight ports. Each port group can be conﬁgured to be modem or direct-connect.

Page 20

IP addresses

IP (Internet Protocol) addresses are composed of 32-bit integers and are used to identify an IP node in the Internet. An IP address can be assigned to a DTC as well as to an individual port on a DTC. IP addresses are usually represented in the following form:

x.x.x.x where x is a decimal number in the range 0 to 255.

Be sure that you:

• Assign a unique IP address to each IP node in your network

• Do not assign network addresses or node addresses that are all 1s or all 0s.

These addresses are reserved.

Special DTC terminology

The following specialized terms are used in this manual.

Board and card

The terms board and card are used in this manual to mean the same thing. For the DTC 16 and DTC 48, the term card is employed, for example, SIC (Serial Interface Card) or connector card. The DTC 72MX and, in general, all other DTC types now use the term board.

CPU/LAN or LAN processor board

Each DTC has a processor board that handles the overall management of the DTC. The processor board is the central processing unit (CPU) of the DTC and contains the ﬁrmware and downloaded software responsible for much of the data communications processing done by the DTC. It also provides the DTC with its connection point to the LAN via an attachment unit interface (AUI) cable and a medium attachment unit (MAU) for ThickLAN connection, or a BNC T-Connector for ThinLAN connection.

Special DTC terminology

In the DTC 16 and DTC 48, the processor board on the DTC is called a CPU/LAN.

In the DTC 16TN and DTC 72MX, the processor board on the DTC is called a LAN

board.

Port groups

In the DTC 16TN and DTC 72MX, the ports are grouped into port groups. Each port group has eight ports. The DTC 16TN has two port groups, and the DTC 72MX has three port groups per board. Each port group can be modem or direct-connect. A port group corresponds to a connector on a board of a DTC 72MX or to a connector on a DTC 16TN.

Before installing DTC Manager/UX

This chapter describes requirements that must be satisﬁed before DTC Manager/UX can be installed.

Even though the product supports up to 4 LAN devices, it is recommended that all LAN devices be located on a single LAN, lan0 (to facilitate the installation procedure), and that DTC Manager/UX be located on this same LAN. DTC Manager/UX is, however, compatible with other LAN devices that are connected to the LAN by means of a bridge or hub.

Note DTC Manager/UX does not provide support for router-connected devices.

Hardware requirements

Ensure that you have the following:

• an HP 9000 Series 700 or 800

• LAN/9000 LINK hardware components including a minimum of one LAN interface card (LANIC) and up to 4 LAN devices

• for an 800 system, a terminal connected to a MUX

• at least 20 Mbytes of free disk space for the DTC Manager/UX software

• additional disk space depending on the number of DTCs, the DTC types, and the space you need for upload files1 during troubleshooting

The upload ﬁles are located in the /var/opt/dtcmgr/upload directory. You can save up to three upload ﬁles from each DTC. When three upload ﬁles have been saved, DTC Manager/UX overwrites the ﬁrst one again. The disk space needed is:

• 1 Mbyte for each upload file from a DTC 16 or DTC 48

• 3 Mbytes for each upload file from a DTC 16TN

• 5 Mbytes for each upload file from a DTC 72MX

1 Only upload DTC ﬁles if instructed to do so by an HP engineer.

Page 24

Note This note only applies to DTC 48s and DTC 16s.

DTC 48s with a date code less than 3110 require a memory extension and must be upgraded with the DTC 48 Upgrade Kit (HP product 2348A). DTC 48s with a date code of 3110 or later and DTC 16s do not require a hardware memory extension.

Note The following DTC-installable cards are not supported on a DTC being managed on

an HP 9000 system by the DTC Manager/UX software:

- X.25 Synchronous Network Processor card

- Telnet Access Card.

Software requirements

Ensure that you have the following software installed and operational on your HP 9000:

• HP-UX Operating System version 10.x or 9.x for your HP 9000 series.

• Internet Services

• LAN/9000

Supported terminals

The following terminals are supported with the DTC Manager/UX:

• HP compatible terminals with programmable function keys and on-screen display of function key labels

Installing DTC Manager/UX

This chapter describes how to install DTC Manager/UX software and prepare the environment for the required daemon processes. Instructions are provided for HP-UX 10.x and HP-UX 9.x.

It is presumed that the HP-UX operating system, LAN/9000, and Internet Services are installed and operational on your site.

Installation considerations

You can install the DTC Manager on an upgraded HP-UX 10.x system in much the same way as if you were installing from scratch. If you are installing DTC Manager on an upgraded system, check that the product ﬁles are in the correct location.

A DTC Manager migration will occur as part of the installation process. You will have to reset your DTCs which ensures that the upgrade and migration have been successful (see Resetting a DTC Board for more information). You can display a list of managed DTCs using the command dtclist -c.

For more information on migrating from HP-UX 9.x to HP-UX 10.x, refer to the document Upgrading from HP-UX 9.x to 10.x version B.10.01, part number B2355-90050.

Before you can run DTC Manager/UX, you must conﬁgure certain parameters in the

/etc/rc.config.d/netdaemons ﬁle. This is necessary to ensure that the

required daemons will be started automatically when your system is rebooted.

Checking the name of LAN device file

1 Execute the lanscan command to display the list of physically connected LAN

devices on your system.

2 Look for the Net-Interface Name defined in the information displayed by

lanscan. Identify the LAN device file name that corresponds to the LAN on which your DTCs are connected (lan0, for example).

Configuring the netdaemons configuration file

The /etc/rc.config.d/netdaemons conﬁguration ﬁle contains data related to Internet Services.

1 Open the netdaemons configuration file with your text editor (or usech_rc) and

go to the following lines:

export START_RBOOTD=0 export RBOOTD_DEVICES=

To make the rbootd daemon start automatically when the system is booted, ensure that the value at the end of the START_RBOOTD line is set to 1 as shown below.

export START_RBOOTD=1

Note No space is allowed after the equal (=) sign.

2 Verify that all LAN devices connected to the DTC(s) are declared in the

RBOOTD_DEVICES line.

Note The DTC Manager supports up to four LAN devices.

Enter the full path name of each LAN device (separate each device name with a space) as shown below:

Version 10.00/10.01/10.10/10.20

export RBOOTD_DEVICES=”/dev/lan0 /dev/lan1 /dev/lan3”

From Version 10.30

export RBOOTD_DEVICES=”lan0 lan1 lan3”

Page 29

Installing DTC Manager/UX with HP-UX 10.x

Note Quotation marks are mandatory if you are declaringmore than one device and a space

is not allowed after the equal (=) sign.

Caution Do not remove any existing LAN device declarations from this line. This information

might be needed for other system functions.

3 Save the file (if you made any modifications) and exit the editor.

Running the daemons without rebooting

DTC Manager/UX cannot run without the required daemon processes.

Note The netdaemons configuration file must contain the values described in the

previous section before you can start the daemons without rebooting your system.

Normally, the daemons are started automatically each time you boot your system. If you do not want to reboot your system at this time you can start the daemons manually by following the steps below:

1 If the required daemons are not already running on your system, start them by

entering:

/sbin/init.d/rbootd start

to start the rbootd daemon.

2 Enter:

/sbin/init.d/dtcmgr start

to start the dtcnmd and dtcnmp daemons.

Proceed to the next section to verify that the daemons are running.

Page 30

Installing DTC Manager/UX with HP-UX 10.x

Verifying that the daemons are running

1 Use the ps -ef command to check the daemons.

To check whether rbootd is running, use:

ps -ef |grep rbootd

To check whether dtcnmd and dtcnmp are running, use:

ps -ef |grep dtcnm

2 Look at the rbootd and dtcnmd log files to check for errors when the daemons

were started up. Execute the HP-UX tail command from the shell prompt to look at the log ﬁles.

Make sure that the tail command shows enough information.

Note The following commands are for HP-UX version 10.0 (before 10.30):

tail /var/adm/rbootd.log Sat Jan 1 08:48:46 2000 : STARTUP Sat Jan 1 08:48:47 2000 : INITIALIZATION COMPLETE

tail /var/opt/dtcmgr/log/dtcnmd.log Sat Jan 1 08:48:55 2000 : STARTUP Sat Jan 1 08:48:56 2000 : INITIALIZATION COMPLETE

DTC by switching it off and then on (power off/on). This completes the installation of the DTC Manager/UX. You can now use

DTC Manager/UX commands.

Page 32

Installing DTC Manager/UX with HP-UX 10.x

Verifying the software version

At the prompt, type the following command:

what /opt/dtcmgr/sbin/dtcdiag

You will see a line similar to the following which will show your software version:

DTC Manager/UX: Revision A.14.4A.030 copyright ...

software version

If you don’t want DTC Manager to be started automatically

DTC Manager is automatically started by default when your system reboots. You may want to disable this feature (for troubleshooting for example). To disable automatic startup you need to modify the START_DTCMGR parameter in the

/etc/rc.config.d/dtcmgr conﬁguration ﬁle.

Open the /etc/rc.config.d/dtcmgr ﬁle with your text editor (or use ch_rc) and change the START_DTCMGR=1 parameter to START_DTCMGR=0 and save the ﬁle.

Removing DTC Manager/UX

If you need to remove DTC Manager/UX software from your system use the

swremove utility.

Caution If you use swremove, all DTC Manager ﬁles will be permanently removed (you

cannot recover them). This includes all conﬁguration, log and status and upload ﬁles.

Stopping the daemons

Use the command /sbin/init.d/dtcmgr stop to stop the program daemons.

Other file-handling features

For information on other ﬁle-handling features that you should consider when installing DTC Manager, see “Managing DTC conﬁguration ﬁles” on page 38.

Page 33

Installing DTC Manager/UX with HP-UX 9.x

The DTC Manager/UX software is installed using the update command on systems running HP-UX 9.x. The update command is described in the manual Installing and Updating HP-UX.

Installing the software

1 Ensure that you are logged in as root and that you are at the root directory. 2 Ensure that your fileset version matches the version of your HP-UX operating

system.

3 Load the DTC Manager/UX product files on the tape drive attached to your

system.

4 Note the device file name of that tape drive. You need to know the device file

name of the tape drive when verifying the source location using update.

5 To install the software, run the HP-UX update utility in interactive mode by

typing this command at the shell prompt:

update

6 Look at the source device file name displayed on the screen. If your source is

different, then go to step 7. If your source is the same, go to step 11.

7 Select Change Source or Destination from the main menu. 8 Select From Tape Device to Local System... from the main menu. 9 Verify that the device file name in the Source: field refers to the tape drive with

the product software tape. If necessary, change the device file name to the tape drive that you are using.

The Destination Directory: ﬁeld contains a / (slash) and should be left as it is. 10 Press the Done function key. 11 Select the Select All Filesets on the Source Media -> menu item. 12 Select the Start loading now ... item. 13 The update utility checks available disk space and then asks you to confirm that

you want to install the filesets.

The update utility loads the ﬁlesets, runs the customized scripts for the ﬁlesets

and the migration tool to migrate to the version of DTC Manager/UX being

installed.

Page 34

Installing DTC Manager/UX with HP-UX 9.x

Verifying the installation

1 After update has terminated, check that the installation was successful. Execute

either the HP-UX more command or the tail command to look at the file

/tmp/update.log. The file /tmp/update.log file contains the installation

status (successful or unsuccessful). If you use the tail command make sure enough of the file is displayed for you to see the status.

more /tmp/update.log

tail /tmp/update.log

2 Look for the message:

* Customize script for fileset DTCMGR succeeded.

which indicates that the DTC Manager/UX software was correctly installed.

Note The message WARNING : No DTC configuration files have been found indicates

that there were no previous DTC configuration files to be updated from the old version to the new version. The WARNING does not mean that the installation was not successful. If any DTCs were updated, you would see the names of those DTCs.

3 If the installation is not successful, review the hardware and software

requirements in chapter 2 to ensure that your environment meets the management software's requirements. Review the update procedures in the Installing and Updating HP-UX manual.

4 If you have successfully installed the software, go to the next section “Checking

the Name of LAN Device File”.

Checking the name of LAN device file

The installation program assumes that the LAN device ﬁle is called /dev/lan0. It starts up two daemons using /dev/lan0 as the LAN device ﬁle name. It also adds a line to the /etc/rc ﬁle to ensure that these daemons are automatically started up when the system is booted.

Page 35

Installing DTC Manager/UX with HP-UX 9.x

However, if your LAN device ﬁle name is not /dev/lan0, you must start the daemons manually and edit the ﬁle /etc/rc yourself. The steps below describe how to check the LAN device ﬁle name.

1 Execute the lanscan command to display the list of physically connected LAN

devices on your system. 2 Look for the Net-Interface Name defined in the information displayed by

lanscan. Identify the LAN device file name that corresponds to the LAN on

which your DTCs are connected. 3 If the LAN device file name that corresponds to the LAN on which your DTCs

are connected is indicated as lan0 (full path name: /dev/lan0), your

installation is correct. Take the following steps to complete the installation:

a If you are upgrading from a previous release of DTC Manager/UX, execute

the following command for each DTC:

dtcreset dtcname

b then configure your DTCs using DTC Manager/UX. 4 If the LAN device file name that corresponds to the LAN on which your DTCs

are connected is not indicated as lan0 (full path name /dev/lan0), go to the

next section.

Modifications for LAN device file names other than /dev/lan0

If /dev/lan0 is not your LAN device ﬁle name, there are two modiﬁcations required. You must:

• start the rbootd and dtcnmd daemons with the correct LAN device

• edit the file /etc/rc to ensure that these daemons are automatically started up

when the system is rebooted.

The rbootd daemon handles the download of a DTC when it is switched on or reset. The dtcnmd daemon handles the transmission of network management data from the system to the DTC ( for more information about these daemons refer to the man pages).

Page 36

Installing DTC Manager/UX with HP-UX 9.x

1 Start the rbootd and dtcnmd daemons manually by typing the following

commands at the shell prompt:

/etc/rbootd landevice /etc/dtcnmd landevice

The landevice is the LAN device ﬁle name that you found on page 35 in step 2. It is the LAN interface card that connects your HP 9000 to the LAN. This is the same LAN that the DTCs are on.

Example: If the LAN device ﬁle name, listed by lanscan, which corresponds to the LAN on which your DTCs are connected, is lan1, type the following:

/etc/rbootd /dev/lan1 /etc/dtcnmd /dev/lan1

2 Edit the /etc/rc file to ensure that the rbootd and dtcnmd daemons are

automatically started up when you reboot the system, as follows: a Display the file /etc/rc. b Ensure that the shell variable $RBOOTD_DEVICES is declared and that it

includes the LAN device file name corresponding to the LAN on which the DTCs are connected.

c If the shell variable $RBOOTD_DEVICES is set for multiple LAN device file

names, replace the line in the file /etc/rc that reads:

if /etc/dtcnmd $RBOOTD_DEVICES

if /etc/dtcnmd landevice

Example: If the LAN device ﬁle name that corresponds to the LAN on which your DTCs are connected is /dev/lan1, then you would enter the following line

if /etc/dtcnmd /dev/lan1

Verifying that the daemons are running

1 Use the ps -ef command to check the daemons as follows.

To check whether rbootd is running, use:

ps -ef |grep rbootd

To check whether dtcnmd and dtcnmp are running, use:

ps -ef |grep dtcnm

Page 37

Installing DTC Manager/UX with HP-UX 9.x

2 Look at the rbootd and dtcnmd log files to check for errors when the daemons

were started up.

Execute the HP-UX tail command from the shell prompt to look at the log ﬁles.

Make sure that the tail command shows enough information.

tail /usr/adm/rbootd.log

Tue Sep 10 14:00:23 1992 pid=1234: STARTUP

Tue Sep 10 14:00:23 1992 pid=1234: INITIALIZATION COMPLETE

tail /usr/adm/dtcnmd.log

Tue Sep 10 14:00:23 1992 : STARTUP

Tue Sep 10 14:00:23 1992 : INITIALIZATION COMPLETE

These tail commands show you the last few lines of the log ﬁle. This log ﬁle is

the location that reports whether the process is running. These log ﬁles also

contain all the error messages that might have occurred during startup and

running of the daemons. 3 If the log files indicate INITIALIZATION COMPLETE, you can now use the

DTC Manager/UX commands and then configure your DTCs using

DTC Manager/UX. 4 If you are upgrading from a previous release of DTC Manager/UX, execute the

following command for each DTC:

dtcreset dtcname

This completes the installation of the DTC Manager/UX.

Verifying the software version

At the prompt, type the following command:

what /etc/dtcdiag

Look for a line similar to this:

DTC Manager/UX: Revision A.14.3B.000 copyright ...

software version

Page 38

Managing DTC conﬁguration ﬁles

Managing DTC configuration files

The following section contain information on how to manage DTC conﬁguration ﬁles.

Automatic protection of configuration files

An automatic lock feature protects the integrity of the DTCs new data. The lock mechanism becomes effective when you run update in HP-UX 9.x, swinstall in HP-UX 10.x, or when a new DTC is added. All DTCs remain operational. However, certain DTC management and conﬁguration functions are temporarily disabled until the related DTC is reset (rebooted).

Automatic backup of DTC Manager files

If there is a previous version of DTC Manager software installed on your system, a special script ﬁle will create a backup copy of the old version when you run the update or swinstall utility. Complete details of the software installation are recorded in the update.log ﬁle in HP-UX 9.x or the swagent.log ﬁle in HP-UX 10.x.

Automatic upgrade of DTC configuration files

You do not have to reconﬁgure each DTC after upgrading to a new version of DTC Manager/UX. The DTC conﬁguration ﬁles created by older versions are automatically converted by a utility when you use the command update in HP-UX 9.x or swinstall in HP-UX 10.x.

Complete details of the procedure for HP-UX 9.x are recorded in the ﬁles

/tmp/update.log and /usr/adm/dtcupgrade.log.

Complete details of the procedure for HP-UX 10.x are recorded in the ﬁles

/usr/adm/sw/swagent.log and /var/opt/dtcmgr/log/dtcupgrade.log.

Page 39

Using dtcconfig

This chapter provides information about the DTC conﬁguration procedure and describes the basic use of the menu-driven conﬁguration utility dtcconﬁg.

The following dtcconﬁg operations are covered:

• running dtcconfig

• choosing a menu item from the DTC Configuration Main Menu

• entering values at the DTC configuration menus

• using the DTC configuration function keys

• using the shell function key

• getting help

• exiting from a task or from dtcconfig.

Configuration guidelines

A DTC must have the following in order to function correctly:

• functional software —enables it to access the LAN, support networking

• configuration information —information on how the DTC and its boards,

A DTC only contains some software in ROM, so the functional software and the

conﬁguration information must be downloaded from the DTC Manager to the

DTC.

When a DTC is powered-on or reset, it runs a series of self-tests, then sends a

message requesting a software and conﬁguration download. The DTC Manager

that has the ﬁles for the DTC responds by downloading the functional software

and the conﬁguration information, and the DTC is then managed by the system

from which it received its download.

The conﬁguration information for a DTC is contained in a ﬁle which is created,

modiﬁed and stored on the DTC Manager which “owns” the DTC.

protocols, and manage connections

ports and connections should behave

Page 40

When the DTC is switched on, it is conﬁgured with:

• information that the DTC sends to the manager (such as the number of boards)

• user-defined settings

• and other parameters such as the DTC IP address that you enter when you add a new DTC to the configuration.

In most cases you can successfully conﬁgure your DTCs with information contained in chapter 5. This will enable you to connect terminals to your DTCs. If your site requires a more complex conﬁguration refer to the appropriate chapter later in this book.

To start the dtcconﬁg utility

To start the dtcconfig utility

Once you have installed the DTC Manager/UX you are ready to conﬁgure your DTC.

Note The dtcconfig command requires superuser privileges.

Make sure you logon as root or type the HP-UX su (superuser) command.

At the shell prompt, enter:

dtcconfig

The complete dtcconﬁg command syntax is as follows:

dtcconfig [-a] [-l loglevel] [-L logfile]

Parameter Description

-a Appends the log messages from this dtcconﬁg execution to the existing dtcconﬁg log ﬁle. By default, executing dtcconﬁg overwrites the log ﬁle. The default log ﬁle is /var/opt/dtcmgr/log/dtcconfig.log.

-l

loglevel

-L

logfile

Sets the amount of information that will be logged in the log ﬁle for this dtcconﬁg execution. Specify one of the following logging levels:

0 Logs only startup and termination messages of dtcconﬁg. 1 Logs serious and fatal error messages and level 0 messages.

This is the default logging level.

2 Logs warning and informational messages and level 1

messages.

Speciﬁes an alternative log ﬁle that dtcconﬁg should use to log the messages. The default ﬁle is /var/opt/dtcmgr/log/dtcconfig.log .

When you execute the dtcconﬁg command, the console screen will display the DTC Conﬁguration Main Menu.

Page 42

Using the dtcconﬁg menus

Using the dtcconfig menus

The DTC conﬁguration tool (dtcconﬁg) provides menus, ﬁelds, and function keys to help you conﬁgure your DTC devices. It has three types of menus:

• Main menu: used to access other menus and functions.

• Actions menu: provides you with a selection of possible actions you can take

from the current screen.

• Data acquisition menu: provides you with a list of possible field values. This menu is displayed by pressing the Help (F1) function key.

You can select a menu item in one of two ways:

• Use the arrow keys or Tab to move from one item to the next. Once the desired menu item is highlighted: press Return, or the Select Item or Select Action (F4) function key to start the operation.

• Type the first character of the menu item (for example, a for Add DTC Conﬁguration). The DTC manager immediately executes the command associated with that letter (you do not have to press Return). If several options start with the same letter, enter the letters of the option until it is unique (for example, con for the Configure option and cop for the Copy function). This

abbreviated method does not work when selecting from a list of valid field options such as found in a HELP screen.

If you enter an incorrect value for a ﬁeld, an error message window appears. Read the message and press the space bar to return to the screen and to correct the entry.

The following keyboard keys are used to enter information at the various dtcconﬁg screens:

• Tab and arrow keys. If the Tab key does not let you move to another field, try using the arrow key.

• Space bar. When an error message is displayed, you must press the space bar to continue.

• Function keys. Explained in the next section, function keys vary for different screens.

• Return key, Perform Task (F4), and Done (F4) function keys. Read the popup window message or look at the bottom of the screen to know which of these keys to press.

Page 43

Using the function keys

Use the function keys (indicated at the bottom of the screen) to execute functions.

Note Note that the function keys are context sensitive and perform different operations

depending on the current screen.

The following keys have speciﬁc functions:

(F1)–Help: used to obtain a summary of information for a particular ﬁeld or menu item. For the modify and delete functions of dtcconﬁg, the Help function key provides you with a list of DTCs to modify or delete. This function key is on almost every screen.

(F3)–Shell: Used to temporarily access the HP-UX shell. After you have ﬁnished entering shell commands, type exit to return to the dtcconﬁg utility. This function key does not appear on every screen. You cannot execute another dtcconﬁg, dtcdiag, dtcping or dtcmodifyconfs command from the shell because only one instance of these commands can run at a time.

(F4)–Multi function Key

(F5)–Actions Menu: Used to access the Actions Menu.

(F6)–Default Values: Used to choose a set of default values for a set of ﬁelds.

(F8)–Exit: Used to leave the current screen. Refer to see “Exiting from dtcconﬁg”

on page 46 for more information. This function key is always available.

Page 45

Using the editing keys

You use the dtcconﬁg editing keys to enter values in the various ﬁelds.

You should note that some of the editing keys do not function as they normally would if you were editing text. Speciﬁcally, the following keys behave differently:

• [Clear Line]—If you use this key while entering a value in a field, you do not get a response. The line is not cleared and you must return to the beginning of the field to start entering the value again.

• [Delete Line]—This key deletes all the data on the line. However, in order to enter a new value on that line, you must move the cursor to the beginning of the line.

• [Insert Char]—It is best to make sure that Insert Character mode is off. In some fields, Insert Character mode is functional. However, in most fields, using it results in no action from the keyboard (that is, the keyboard does not respond when you try to type a value into a field).

• [Clear Display]— This key is disabled.

• [Insert Line]— This key is disabled.

Using the editing keys

• [Enter]—This key should not be used and has unpredictable results. Use the Return key.

Refreshing the screen

Sometimes the screen may become difﬁcult to read due to line or data rate problems. If this happens, type [Ctrl]-L and the screen will be redisplayed in its correct form. If this continues to happen, check the line rate and terminal conﬁguration and ensure that it matches the DTC port conﬁguration.

Page 46

Getting help

There are three areas of online help:

• The Help for Using DTCconfig menu item from the main menu. Selecting this menu item displays general dtcconfig help information. This is an overview of the dtcconfig screens and the keyboard keys.

• Help (F1) function key. Almost all dtcconfig screens include a Help function key. Pressing this function key provides information about the field you are currently in.

• List of DTCs. From the Delete DTC Configuration or Modify DTC Configuration screens, the Help (F1) function key displays a list of DTCs for you to choose.

Exiting from dtcconfig

After pressing the Exit Task (F8) function key several times, you eventually return to the dtcconﬁg main menu. From the main menu, when you press the Exit DTCconf (F8) function key, a pop-up message prompts you to quit or not quit. Enter a y to quit. Enter an n to remain in dtcconﬁg.

Note If you made modifications related to IP addresses, (for example, if you create a new

DTC or modify the configuration of the LAN address for an existing DTC), dtccheckip will be launched automatically. You will only get output if there are duplicated IP addresses.

Page 47

Adding DTCs

This chapter describes how to add one or more DTCs to the set of DTCs managed by DTC Manager/UX.

Note 150 is the maximum number of manageable DTCs.

Note The instructions in this chapter presume that DTC Manager/UX is already properly

installed and that you are familiar with the basic use of the dtcconfig menus and function keys as described in chapter 4.

Procedure overview

When a DTC is added, a basic conﬁguration is created on the management system. This initial conﬁguration is created according to the user-deﬁned DTC default parameters.

DTC parameters are initially set to HP factory-deﬁned default values. If you need to modify these values you can use the dtcconﬁg utility’s Modify DTC Conﬁguration option to do so.

Refer to chapter 9 if you want to set your own default parameters.

Before the DTC begins a download process, it communicates its hardware conﬁguration to the management platform. The DTC Manager/UX uses this information to automatically update its system image of the DTC. Physical settings in the DTC conﬁguration, such as added or deleted boards, as well as whether a port group is modem or direct are reported to the DTC Manager/UX. All hardware changes are automatically made to your DTCs.

Add DTC Conﬁguration

To create a default conﬁguration for new DTCs (where all ports are conﬁgured as terminal ports):

1 Ensure that the DTCs are properly connected to the LAN and then switch them

off and then on again.

2 Start the dtcconfig program by typing;

dtcconfig

3 Choose the Add DTC Configuration option from the main menu.

The Add DTC Conﬁguration screen appears (see “Conﬁguration parameter deﬁnitions” on page 50 for an explanation of these ﬁelds).

4 Create a DTC list containing DTCs of one of the four types (DTC 16TN,

DTC 16, DTC 72MX or DTC 48). To configure a DTC 16MX, proceed as if you were adding a DTC 16TN. When managed by the DTC Manager/UX, the DTC 16MX is configured and functions exactly like a DTC 16TN.

• Press Return or TAB, or use the arrow keys to move to each field.

• Use the online help for more information about each field.

• Enter the number of DTCs you want in a list.

Page 49

The ﬁelds of the previous DTCs scroll upward allowing you to enter more DTCs. All of the DTCs must be of the same DTC type (DTC 16TN, DTC 16, DTC 48 or DTC 72MX) and will be set to the same conﬁguration.

Checking the terminal connections

Follow these steps for each terminal connected to the DTC.

1 Press Return. The DTC prompt, usually DTC>, should appear. Enter the

connect command with the IP address1 of the system you want to connect to.

DTC> connect 15.13.12.12 Connection #1 established to mysystem.mygroup.mycorp To return to DTC interface, type <CTRL>K login:

2 If you are not successful, try to modify the configuration of the DTC (refer to

chapter 6). If the DTC does not respond, it probably means that the DTC LAN address is not correct. Delete the DTC and then add it again.

3 If you still cannot establish a connection, go to the troubleshooting section in

chapter 15.

Configuration parameter definitions

DTC Name Enter a name consisting of up to 8 alphanumeric characters. You can include

hyphens (-) and underscores (_) but the ﬁrst character must be alphabetic. The DTC name ﬁeld must not be left blank.

The DTC name is a unique name used by the DTC manager to identify a particular DTC. For simplicity, the DTC name and the nodename portion of the DTC node name are often the same name. However, they are used for separate tasks by the DTC Manager/UX and the system.

1 You can only use a system name here if you have conﬁgured the system name in the DNS server.

Page 51

Conﬁguration parameter deﬁnitions

DTC LAN Address Look for the DTC LAN address on your DTC and enter this value. Ensure that you

enter this address exactly as it is marked on the DTC. If you enter an incorrect DTC LAN address, the DTC will not operate.

Hewlett-Packard has assigned each DTC a unique DTC LAN address which is indicated on an address label as follows:

DTC 16TN—on the back panel near the port connections DTC 16—on the back panel in the upper right corner DTC 48—inside the front panel DTC 72MX—on the back panel on the LAN board

When a DTC is ﬁrst added, the DTC LAN address ﬁeld in the Add DTC Conﬁguration screen indicates 00-00-00. Replace this with your DTC LAN address. The format of the LAN address is usually 08-00-09-xx-xx-xx or 00-60-B0-xx-xx-xx where xx is a hexadecimal number.

Note When configuring a DTC for connection to your HP 9000 system, the IEEE 802.3

protocol is used on the LAN connection. However, for communication between the terminal and the system, the Ethernet protocol is used. Ethernet and IEEE 802.3 LAN protocols are similar, and can coexist on the same physical LAN, using the same physical address configured in the DTC LAN Address field. The address you define here will also be used as the Ethernet address for the DTC.

DTC IP Address Enter a value in the form xxx.xxx.xxx.xxx where xxx is a decimal number from 0

through 255. The address cannot be 0.0.0.0 or 255.255.255.255 which are reserved addresses. Assign a unique IP address to each DTC.

If you use a DNS server, you must ﬁrst add each DTCs IP address and, secondly, conﬁgure the DTC for DNS.

Note In the “Add DTC Configuration” screen, you must enter a value for DTC IP address

even if you do not use the DNS server.

Each DTCs IP address must also be added to your name database, for example the

/etc/hosts ﬁle or the DNS (Domain Name System) server. The/etc/hosts ﬁle

is documented in the manual, Installing and Administering LAN/9000 Software.

This parameter is the IP address of the DTC itself. Do not confuse it with the IP address of the host system, or with the IP address of a port.

Page 52

Conﬁguration parameter deﬁnitions

DTC Node Name Enter a name in three parts, each with a maximum of 16 characters, separated by

periods as illustrated in the example syntax below.

nodename.domain.organization

Each part must start with an alphabetic character and can be followed by a combination of alphanumeric characters, hyphens (-), and underscores (_). As you enter the name, it shifts right to extend beyond the visual line.

The DTC Node Name is a unique node name to identify a DTC within a system or network.

For simplicity, the DTC name and thenodename portion of the DTC node name are often the same name. However, they are used for separate tasks by the DTC Manager/UX and the system.

DTC Type Enter an X or an x in one of these four ﬁelds: DTC 16TN (also use this ﬁeld for a

DTC 16MX), DTC 16, DTC 48, or DTC 72MX. All the DTCs in a list must be of the same type.

Page 53

Modifying DTCs with dtcconfig

This chapter describes how to modify a single DTC with the interactive dtcconﬁg utility. The utility’s Modify DTC Conﬁguration menu allows you to modify a CPU/LAN (or LAN board), board, and/or port of a single DTC.

You can only modify one DTC at a time with dtcconﬁg. If you want to modify multiple DTC conﬁgurations at the same time, use the dtcmodifyconfs command (as described in chapter 10).

Note The instructions in this chapter presume that DTC Manager/UX is already properly

installed and that the DTC you want to modify is physically present on the network and switched on. In addition, it is presumed that you are familiar with the basic use of the dtcconfig menus and function keys as described in chapter 4.

Once you have modiﬁed the DTC, refer to the appropriate chapter to:

• modify CPU/LAN board or LAN board parameters for a single DTC (chapter 7)

• modify terminal, printer port and other parameters on a board of a single DTC (chapter 8)

• copy DTC board and port configurations (chapter 9).

marked.

DTC User Interface Timeout

Specify a timeout value between 5 and 300 seconds for the DTC. The default timeout is 300 seconds. A terminal user using the connect command to connect to a system via the DTC must attempt to connect to the system within this amount of time.

The DTC waits this amount of time before the DTC Terminal User interface is disconnected. Once the terminal has established a connection with a system via the DTC, the timeout is disabled until the user returns to the DTC user interface.

The DTC User Interface Timeout can be enabled and disabled from the Enable

Port Options screen (see “Enabling port options” on page 99). By default, the DTC User Interface Timeout is disabled.

Page 70

Conﬁguring global parameters

User Prompt If you want a user prompt that is different from the default prompt, DTC>, specify a

prompt of up to 16 alphanumeric characters. Non-displayable ASCII characters must be speciﬁed in caret-character format (for example, ^K means Ctrl-K). Use a backslash before a literal caret (^) and a backslash (\).

The User Prompt is the DTC prompt seen by a user at a terminal connected to a DTC. You may want to change the user prompt to the name of your DTC (for example, MYDTC1>) to help you keep track of your DTCs. Only users connected to ports with the switching capability see the prompt. Other users connected directly to a host system do not see the DTC user prompt.

Switching is the ability to connect to more than one computer from a terminal. Switching is automatically enabled for all terminal ports.

Welcome Message If you want to provide a welcome message, enter up to 390 alphanumeric characters.

Non-displayable ASCII characters must be speciﬁed in caret-character format (for example, ^K means Ctrl-K). Put a backslash (\) before a literal caret (^) or a backslash (\) to ensure these characters appear correctly on the screen. The welcome message is an optional parameter.

Do not use the keyboard Enter key (carriage return) to create line breaks in the welcome message. Using the Enter key terminates the DTC conﬁguration steps. Use the ^M^J (Ctrl-M, Ctrl-J) keys to force the text onto the next line.

Enable DTCDF Access

The welcome message is the message displayed on a terminal connected to a DTC when

• a terminal user opens a connection to a port configured for system switching

• a terminal user connected to the DTC user interface issues the “status command”

Only users connected to ports with switching capability see the welcome message. The welcome message is not displayed when a user switches back from a system connection to the DTC user interface.

This ﬁeld enables a Hewlett-Packard support engineer to access DTC memory for troubleshooting. Access is protected by a password. Put an X or an x in this ﬁeld to enable a Hewlett-Packard support engineer access your DTC and to format DTC memory dumps.

Configure DNS/IP Parameters

Use the DNS/IP Parameters Conﬁguration to specify:

• the IP addresses for the DNS (Domain Name System) server

• the IP routing parameters

The DTC sends a DNS request to the DNS server whose IP address is speciﬁed. The DNS server returns the IP address of the requested system. If you specify the IP address of a system with the DTC connect command, DNS is not used.

The IP address format is xxx.xxx.xxx.xxx where xxx is a decimal number from 0 through 255. The IP address can be 0.0.0.0 but cannot be 255.255.255.255. The IP address is unique on the network. An IP router allows connections to nodes on different LAN networks. If an IP router is not deﬁned, then connections cannot be made to systems outside the local subnet.

Default Server Address

Backup Server Address

Default Local Domain

Enter the IP address of the default server you want to use. A DNS server resolves system names to IP addresses for the entire network. For example, if you are at a terminal, you can enter the DTC connect command with a system name instead of an IP address:

DTC> connect host1.hp.com

Enter the IP address of the DNS server to be used if the default DNS server is not available.

Enter the default local domain that you want to use. The DTC uses the speciﬁed local domain name to complete the Domain node name when necessary. If a terminal user enters a node name without a period, the DTC will complete the node name with the default local domain name. For example, if the Default Local Domain is hp.com and a terminal user enters:

DTC> connect host1

the DTC will try to connect to host1.hp.com.

IP Routing parameter definitions

Default IP Router Address

Backup IP Router

Enter the IP address of the default router. The router routes outbound packets for destinations which are not part of the local subnet.

Enter the IP address of the router to be used if the default IP router is not available.

Address

Subnet Mask Enter the subnet mask for this network. The subnet mask has an IP address format of

xxx.xxx.xxx.xxx where xxx is a decimal number between 0 and 255. It must have 255 in the ﬁrst ﬁeld. The subnet mask is an optional parameter.

The subnet mask provides a way to expand the network part of the IP address. The subnet mask is used by IP to check if the datagram should be sent to the destination without routing, or routed to a different destination network or subnetwork.

About subnets

A subnet is a portion of a network deﬁned as a separate network. The subnet mask speciﬁes how much of the address to reserve for subdividing networks into subnetworks. What deﬁnes a subnet is that all the bits in the IP address speciﬁed by the subnet mask (that is all the bits set to 1 in the subnet mask) are the same for all IP addresses in that subnet.

Example: If the subnet mask is:

255.255.255.224 (1111 1111 1111 1111 1111 1111 1110 0000)

then the right-most 5 bits of any address on the subnetwork indicate a node address.

Configuring SNMP parameters

SNMP is an open-systems standard that allows a DTC to be interrogated by any authorized SNMP network management workstation, for example a workstation running HP OpenView Network Node Manager. Security is provided by authorization ﬁlters which list the network management workstations that are allowed to access the DTC.

The SNMP information about the DTC is stored in a MIB (management information base). For example, the MIB contains information such as the physical location of the DTC and whether the DTC should report unauthorized access attempts to the SNMP manager. Two types of MIB are available: MIB-II allows the SNMP manager to access the standard MIB objects; DTC MIB allows the SNMP manager to access the standard MIB objects as well as HP-UX MIB objects.

DTC Manager’s dtcconfig utility provides two screens for SNMP conﬁguration:

• Configure SNMP Authorization Filters—identifies the SNMP managers, the

information that can be requested and whether the managers have write access to the SNMP MIB data.

• Configure SNMP/MIB Data Parameters—defines the SNMP-specific data to

be stored on the DTC.

Configuring terminal and printer ports

Once a port has been conﬁgured, this conﬁguration can be copied and pasted to other ports as described in chapter 9.

To modify several DTCs simultaneously, use the dtcmodifyconfs command as described in chapter 10.

Note For the purposes of the procedures described in this chapter it is presumed that you

have added at least one DTC to the conﬁguration and that it has at least one board in it. It is also presumed that you are familiar with the basic use of the dtcconfig menus and function keys as described in chapter 4.

Any changes you make to the port parameters take effect immediately. You do not need to download the DTC. However, if any terminal users connected to the DTC are running sessions, they will not see the changes until they close the current sessions and start new sessions.

Terminal/Printer Name or IP Address

Enter up to 16 alphanumeric characters or an IP address in this ﬁeld. The characters can include hyphens (-) and underscores (_). The ﬁrst character must be alphabetic. This is an optional ﬁeld that has no value by default.

By entering a name or IP address, you are naming or labeling the port, not the device attached to it. If you disconnect the device and connect it to another port, the device is associated with the name or IP address of the other port. If you want the device to retain its name or IP address, you must reconﬁgure the ports accordingly.

Some key points to consider about using a port IP address:

• The port IP address must be on the same subnet as the DTCs IP address.

• If there is a port IP address for outgoing connections, it is used as the calling address.

• If there is no IP address for the port, the DTCs IP address is used.

• You cannot use same port IP address for more than one DTC pooled port. Be careful about the IP address when you copy and paste boards.

• The per port IP address feature can be used with the Telnet port identification feature and the DTC Device File Access Utilities (DDFA). The port IP address can be associated with a specific pty device file name. Together, these features can be used to provide a pool of ports or identify a specific printer port to the HP-UX spooler. DDFA is part of Internet Services. Refer to the DDFA documentation for more information.

Line Speed Set the line speed to correspond to the line speed of the attached device. To select a

line speed, press the Help (F1) function key and a list is displayed. Line speed choices are 300, 1200, 2400, 4800, 9600, 19200, and 38400 bits per second. Highlight your choice and press Return or the Select Item (F4) function key.

Attached Device Select the type of device physically attached to the port. This adapts the port

behavior to the requirements of the physically-attached device. To select the device, press the Help (F1) function key and a list is displayed. Highlight your choice and press Return or the Select Item (F4) function key.

Please refer to the HP DTC Technical Reference Manual (5961-9820)

The choices are as follows.

• Terminal—the default for direct connect and modem terminal ports

• Printer—the default for direct connect and modem printer ports

• HP 2334/35 Multiplexer

• US Modem—for a modem port with modem behavior set to Standard DCE, DCE High, or DTE (see “Modem Behavior” on page 95).

• European Modem—for a modem port with modem behavior set to Standard

DCE, DCE High, or DTE.

• Data Switch

• US Modem IN OUT

• EU Modem In OUT

• Five Wires Modem.

Bits Parity Bits parity allows you to select the data length (not including start and stop bits) and

the parity you want to assign to the port. Data length is also known as number of bits per character; these bits determine the number of received serial bits assembled to form a character.

The possible values are :

7 bits data length with parity even 7 bits data length with parity odd 7 bits data length with parity forced to 0 7 bits data length with parity forced to 1 8 bits data length with parity none 8 bits data length with parity even 8 bits data length with parity odd

A setting of 8 bits data length with parity none is used by default.

Number of Stop Bits This setting determines the number of stop bits to be used for asynchronuous

characters. Possible values are :

1 stop bit 2 stop bits

The 2 stop bits option could be required for speciﬁc device, such as a bar code reader. The setting 1 stop bit is used by default.

Modem Behavior If you have selected a direct connect port, modem behavior is not used and should

be set to None. The default is None.

Please refer to the HP DTC Technical Reference Manual (5961-9820) for simple modem support.

If you have selected a port on a modem board or port group, select modem behavior by pressing the Help (F1) function key. A list is displayed. Highlight your choice and press Return or the Select Item (F4) function key.

The DTC checks device modem signals and sets up its own modem signals. You may want to enable the automatic connection port option for this port. If enabled, the DTC will establish a connection to the default destination as soon as it senses modem signal activity. See “Default Destination (IP Address or Internet Name)” on page 97. and see “Enable Keep Alive” on page 103.

Terminal modem ports

• None—use for a directly-connected terminal

• Standard DCE—use for a terminal connected to the DTC port via a modem/

multiplexer

• DCE high—use for a terminal connected to a DTC 16TN or DTC 72MX port

via a modem/multiplexer, and where you need an indeﬁnite time-out before pressing Return to connect to the DTC user interface

• DTE—use when the connection to the terminal is initiated by the host

Page 96

Conﬁguring terminal and printer port parameters

Printer modem ports

• None—use for a directly-connected printer.

• Standard DCE—use for a modem-connected printer, where a link is made

at the device.

• DCE high—use for a terminal connected via a modem/multiplexer.

• DTE—use when the connection to the terminal is initiated by the host.

Data Transfer Mode Speciﬁes the data transfer mode to be used when opening the connection on the port.

Possible values are :

ASCII BINARY

If BINARY is used, the DTC does not detect special characters received from the device; all received characters from the device are sent to the system without interpretation.This is also known as transparent mode.

The setting ASCII is used by default.

Escape From Data Transfer Character

Maximum Number of Sessions

Enter the ASCII character you want to use as the escape character that signals when to escape from the data transfer process. Non-displayable ASCII characters are speciﬁed in caret-character (^character) format. The literal caret (^) and backslash (\) are escaped with a backslash. This ﬁeld must be ﬁlled. The default escape (from data transfer) character is ^K (Ctrl-K).

The escape from data transfer character is used at a terminal to switch from the host system to the DTC terminal user interface. This value applies only to terminal ports for which switching is enabled (see “Enable Switching” on page 102).

If switching is enabled when the DTC is conﬁgured, you can logon to a terminal. Press any key on the terminal to get a DTC prompt. You can then logon to your system. Later, if you wish to leave your system but not log off, you enter the escape from data transfer character (Ctrl-K). You see the DTC prompt again and can enter a DTC user terminal interface command. You can even connect to another system. The number of systems you can connect to is determined by the Maximum Number of Sessions.

Specify a value between 1 and 5. The maximum number of sessions is the greatest number of system connections allowed on a terminal at any one time. This value applies only to terminal ports for which switching is enabled.

Page 97

The default is 3 sessions per port.

Conﬁguring terminal and printer port parameters

Number of Systems Sharing Printer

Default Destination (IP Address or Internet Name)

Specify a value between 1 and 5. This ﬁeld applies only to printer ports for which the dedicated printer is disabled. The number of systems sharing printer is the greatest number of systems able to use the printer port at any one time.

The dedicated printer option is enabled or disabled from the Enable Port Options menu. By default, the dedicated printer option is disabled.

The default is 3 systems sharing a printer.

Total number of sessions and shared printers

Maximum number of sessions

Printer sharing 5 x 16 = 80 5 x 16=80 (6 x 8)+40=88 5 x 72 = 360

Enter one of the following in this ﬁeld.

• Nothing—no system is identified (this is the default).

• The Internet Services node domain name—any number of non-empty fields separated by periods (.). Each field may contain alphanumeric characters and hyphens (-).

5 x 16 =80 5 x 16=80 (6 x 8)+40=88 5 x 72 = 360

• An IP address.

If you type C, without specifying a system, you are connected to the default destination.

The DTC connects you to this system when it detects modem or keyboard activity.

The printer is only available to the “default destination” system.

For information on switching, automatic connection, and dedicated printers, see “Enable terminal or printer port options parameter deﬁnitions” on page 101.

Initialization String Enter up to 16 ASCII characters to specify the initialization string. Non-displayable

ASCII characters are speciﬁed in caret-character (^character) format. For example, specify ^M^J for Ctrl-M and Ctrl-J. The literal caret (^) and backslash (\) are escaped with a backslash. This ﬁeld is optional and the default is empty.

If speciﬁed, the initialization string is the string to be sent to the connected terminal or printer port immediately after one of the following tasks:

• resetting a port

• closing a session on a host and returning to the DTC user interface

• logging into a system and typing the escape from data transfer character

• establishing a connection to the DTC user interface for modem connections: the initialization string is sent when all the modem signals are up.
