Additionally Configuring HP-UX for a Terminal

The previous procedure ensured the system side was set up properly; now you are setting up the terminal side.

If the terminal will be used as a console, the default configuration is likely to be correct.
If the terminal will not be used as a console (but rather as an additional serial terminal), you might have to set configuration modes.

From the new terminal, use the function keys to set the terminal's features. In most cases, default settings will be sufficient.




	NOTE: Newer terminals have default modes correct for communicating with HP-UX. If you are uncertain the terminal is configured in default mode, Power off the terminal. Hold `D` key down while powering on. The terminal will power on with correct default modes. Make any adjustments that might be necessary.

Add a getty entry for each new terminal in /etc/inittab. Entries must conform to the pattern id:run_state:action:process, as documented on the inittab(4) manpage. A sample terminal entry resembles the following:
ttp3:2:respawn:/usr/sbin/getty -h -t 60 tty0p3 9600
- ttp3 is a label used by init to identify the action uniquely (see init(1M)).
- The 2 is the run state. Systems are shipped with the multi-user run state (see the initdefault entry in inittab). When the system is running in single-user mode (state s), this process is not executed.
- The respawn tells init to restart the process if it exits.
- The /usr/sbin/getty is the process used to set up serial terminal and modem ports and provide the initial login prompt.
- The -h option ensures that the getty will not hang up the line before setting the port speed.
- The -t 60 is a security option to require that the user login name and password is typed within 60 seconds.
- tty0p3 identifies the port in /dev to which the getty attaches.
- The 9600 (highlighted) does not represent the baud rate. It is a pointer into the /etc/gettydefs file, telling the system side what entry to use. An H entry is also provided for hard-wired terminals. See gettydefs(4).
Invoke the following command to activate the updated /etc/inittab file:
/sbin/init q
Add an (optional) entry to /etc/ttytype. Entries should conform to the format documented on the ttytype(4) manpage. In the following example, 2392 is the terminal type; console and tty0p3 are the device file names in the /dev directory.
2392 console2392 tty0p3
Now that HP-UX is set to communicate with the new terminal, verify that the communication parameters for the terminal correspond to their /etc/gettydefs entries. Instructions on necessary changes will be discussed in “Differences between Console and Terminal Configuration ”, the next section.
With the configuration complete, your terminal should display a login prompt. If no login is displayed, press Return several times. If a prompt fails to appear, consult the “Troubleshooting Terminal Problems ” toward the end of this chapter.

Differences between Console and Terminal Configuration

As shipped, HP terminals are configured properly for use as a system console. To use the terminal as a serial terminal, the parameters shown in Table 3-2 “Key Terminal Configuration Parameters ” might require configuration in /etc/gettydefs.

Table 3-2 Key Terminal Configuration Parameters

Parameter	Console (as shipped)	Serial Terminal (hard-wired) ^[1]	Serial Terminal (via modem)
Data bits	8	8	7
Parity	no	no	even
Default speed	9600 ^[2]	9600	300^[2]
^[1]These are the parameters set for the H entry in `/etc/gettydefs`, and can be used for terminal configuration in `/etc/inittab`. ^[2]Sending a Break will cause the speed to change in the sequence shown in `/etc/gettydefs`.

Running Screen-Oriented Applications on a Terminal

To run screen-oriented applications (such as SAM or swinstall) on a terminal that is not being used as a console, you can use the H setting in /etc/gettydefs. As shown in Table 3-2 “Key Terminal Configuration Parameters ”, this will give you 8 data bits and no parity, which are required by screen-oriented applications.

Edit the getty entry in /etc/inittab so that the device special file for the terminal points to the H entry in /etc/gettydefs.
ttp2:234:respawn:/usr/sbin/getty -h tty0p2 H
Reissue the /sbin/init q command to activate the updated /etc/inittab file.

See gettydefs(4) in the HP-UX Reference.

Configuring a Non-HP Terminal as a Console

HP supports Wyse 60 terminals with native ASCII keyboards, VT320, and VT100 compatible (as defined by DEC VT420) terminals, in their default power-on configuration as system consoles for HP 9000 Series 800 E Family computers. Also, HP 700/60 terminals can be configured to emulate the non-HP consoles. Only HP terminals are supported as system consoles on other HP 9000 Series 800 computers.

Two HP MUX interface modules support configuration of a non-HP terminal console, provided you have the correct firmware version:

Access port MUX16 (part number A1703-60022 for Series 800 HP-PB) with firmware version Rev 2.30 datecode 3341. (If you installed the card, you should have recorded the firmware revision on a worksheet in Appendix D.)
The access port MUX module integrated into the core I/O card of Model I computers.

If you are configuring a non-HP terminal or terminal emulation, proceed through the instructions provided in the following sections, and note the limitations described in “Limitations to Non-HP Terminal Emulation”.

Configuring a DEC 420 Terminal to Emulate VT100 or VT320 Mode

The DEC VT100 and VT320 terminals will work in their default settings with HP-UX. For a VT420 terminal to work in HP-UX, it must be configured to emulate either a VT100 or VT320 terminal, as follows:

Install the hardware, as described in the terminal's manual.
Enter set-up mode by pressing the F3 key.
1. Select Default and press Return.
2. Select General and press Return.
3. Set the Mode.
  - To emulate a VT320, select VT400 Mode, 7 bit Controls.
  - To emulate a VT100, press Return until the selection reads "VT100 Mode."
4. Set the ID.
  - To emulate a VT320, select VT320 ID.
  - To emulate a VT100, select VT100 ID.
5. Return to the main settings and save the configuration. Then press the F3 key to exit set-up mode.
Table 3-3 “Configuration Values for vt100 Compatibility ” shows the correct values for a Model VT420 terminal set up to emulate a VT100.

Your VT420 terminal is now configured for use as an HP-UX system console. Please be aware that the configuration is based solely on the VT100 default configuration.

You may notice the following differences between the DEC VT100, VT320, or VT420 terminals and an HP terminal:

Table 3-4 Unique Definitions of VT100 Keys

Key	Meaning
Backspace	Sends Delete character (octal \177) instead of Backspace

Using an HP 700/60 Terminal in DEC Mode

If you have reason to use an HP 700/60 terminal in DEC-emulation mode, you might wish to change the operation of the Backspace key. You can do so by using the HP 700/60 terminal's set-up menu.

Enter the Setup menu and proceed to the Keyboard Configuration menu.
Set the Backspace key from Delete to Backspace.
Save the Keyboard Configuration.
Log out, then log back in again. Your keyboard will now be set to erase characters correctly.

By default, the backspace key on both DEC terminals and emulation is configured as DEL, echoes ^? on the screen, and does not erase. To set the key to erase, execute an stty command as follows:

stty erase "^?"

Input the ^ and ? characters as separate keystrokes and be sure to enclose them in quotation marks.

HP 700/60 terminals in VT320 mode uses control-H for backspace.

You can set this up in your .profile or .login file.

Configuring the Wyse 60 Terminal

Configure the Wyse 60 terminal for use as an HP console by executing the following set of instructions:

Install the hardware, as described in the terminal's manual.
Configure HP-UX to use the Wyse 60 terminfo file to communicate with the terminal. To do so, set the TERM variable to wy60 by executing the following command for Posix or Korn shell:
export TERM=wy60

Your Wyse 60 terminal is now configured for use as an HP system terminal. Please be aware that the configuration is based solely on the Wyse 60 default configuration. If further adjustment is required, use the terminal values provided in Table 3-5 “Wyse 60 Default Configuration Values ”.

Limitations to Non-HP Terminal Emulation

Non-HP terminal support has limitations to usage, particularly in the area of keyboard differences. Observe the following:

The CUE startup screen will work with non-HP terminals only if the -T option is used with cuegetty (see cue(1) and cuegetty(1M) in the HP-UX Reference).
All HP terminals use screen buffers for the page-up/Prev and page-down/Next functions. Non-HP terminals and terminal emulations do not provide these keys; they rely on applications to handle them.

Wyse 60 Emulation Limitations

The Wyse 60 overloads the meaning of various ASCII control characters. As a result, the behavior of some control characters may not be as the user expects.
Use the DEL key (located next to Backspace) to backspace. If using HP 700/60 with a PC-AT keyboard in Wyse60 mode, the DEL key is located in the bottom row of the number pad.
Unlike HP terminals, which provide two lines, Wyse 60 terminals provide a single line to display softkey labels. Sometimes, this may result in truncated softkey labels. For example, the "Help on Context" label for F1 might appear as "Help on C."

DEC VT-Series Limitations

Two different kinds of keyboards are available for DEC terminals — a DEC/ANSI keyboard with programmable function (PF) keys and a PC-AT keyboard, which does not provide programmable function keys.
The function keys F1 through F4 on the DEC/ANSI keyboard are preassigned. Different keys are used for its programmable function (PF) keys. Certain applications, such as Dialog Manager based applications, will remap some of the keys. Other commands may or may not have any keyboard remapping.
The DEC PC-AT keyboard does not provide PF1, PF2, PF3, or PF4 keys. PF4 can be mapped on a DEC PC-AT keyboard to the - key.
Table 3-6 “Function Key Mappings ” compares use of function keys on the DEC/ANSI keyboard, DEC PC-AT keyboard, and an HP keyboard. (Function keys on Wyse keyboards are consistent with HP keyboards.)

Table 3-6 Function Key Mappings

HP or Wyse60	DEC/ANSI keyboard in VT100 or HP700/60 in VT100 mode	DEC/ANSI keyboard in VT320 or HP700/60 in VT320 mode	DEC PC-AT keyboard
F1	PF2	PF2	`/` key
F2	PF1	PF1	`NumLock`
F3	space bar	space bar	space bar
F4	PF3	PF3	`*` key
F5	return	F10, [exit]	F5
F6	none	none	none
F7	none	F18	first unlabeled key to right of Pause/Break
F8	none	F19	second unlabeled key to right of Pause/Break

Many applications use Tab for forward navigation and ShiftTab for backward navigation when moving from one field to another. Users having DEC terminals or using terminals in DEC emulation modes will find that these two actions are indistinguishable. Therefore, you must navigate in a circular fashion to return to a desired field (that is, Tab forward through the menus).
DEC terminals do not support softkey menus; thus, no such menus are displayed on these terminals.
