HP-UX System Administrator's Guide: Routine Management Tasks

directory contains an entry wy100, you have probably found the correct file. To

be sure, examine the contents of the file with more. You will see a screen full of

special characters, but near the beginning you will see wy100|100|wyse 100.

This verifies the correct file and shows that you can refer to the Wyse 100 by any

of the names wy100, 100, or wyse 100.

If there is a terminfo file for the terminal you want to add, skip the next step and

go to Step 4.

If there is no terminfo file for the terminal you want to add, you will need to

create one. See the next step for details.

3. To create a terminfo file, follow the directions in terminfo(4).

To adapt an existing file, follow these steps:

a. Log in as superuser.

b. Make an ASCII copy of an existing terminfo file. For example, make a copy

of the file /usr/share/lib/terminfo/w/wy100 by entering:

untic /usr/share/lib/terminfo/w/wy100> new_file

c. Edit the new file to reflect the capabilities of the new terminal. Make sure you

change the name(s) of the terminal in the first line.

d. Compile the new terminfo file:

tic new_file

For more further information, see tic(1M) and untic(1M)

4. Set the user’s TERM variable in the appropriate login script (either .profile for

Korn and POSIX shell users or .login for C shell users in their home directory)

to any of the names you uncovered in Step 2. For example:

export TERM=wy100 (Korn or POSIX shell)

setenv TERM wy100 (C shell)

The default versions of these scripts prompt the user for the terminal type upon

with the terminal name. For example:

TERM = (hp) wy100

You can also set the TERM variable with the /sbin/ttytype command.

Troubleshooting Problems with Terminals

There are a number of terminal related problems that can occur. Many of these result

in a terminal that appears not to communicate with the computer. Other problems

cause “garbage” to appear on the screen (either instead of the data you expected or

intermixed with your data).

This section primarily addresses problems with alpha-numeric display terminals;

however, many of the steps discussed here can also be applied to problems with terminal
