Tintin:
Please expand on your question.

Do you mean setting the tty characteristics? If so, use stty.
Do you mean the actual tty device?  If so, then you can't change it.

We are two different environments.
Example: TEST and DEV

in TEST when I type tty the following displays:
/dev/pts/tF

in DEV when I type ttyp the following displays:
/dev/pts/tc

How do I change the DEV tty to tF from tc?

Thanks

Tintin:
Pseudo devices (/dev/pts) are assigned on a first come first served basis.  They will potentially be different everytime you login depending on who else has logged in previously.

waipahu:
I think I'm asking the wrong question. You are correct, it can change everytime I log on.
My keyboard mapping is screwed up on the the new environment.  All the keys work accept
the backtab key.  It displays the ~ character.
Do you think my environment or profile setting is set wrong?

What steps do I need to take to fix this problem.  My terminal emulation software is the same and the keyboard mapping is the same.

Tintin:
Check the contents of your .profile.  They probably differ between your test and dev environments.

omarfarid:
Hi,

Please check the value of the TERM env. variable in both environments. You probably will see that they are different.

If this is the case, then in your login initiation files (e.g. .profile) you may  add a check for the TERM type and then use stty to set the right characteristics for you.

For example, in .profile:

case $TERM in
vt100)
stty ...... ;;
vt220)
stty .... ;;

esac

Please note that you need to put the right stty command in place of stty .....

Also, not the ;; and esac which are required.

JJSmith:

Can you confirm that the command:

tset -s

returns the same result in TEST and DEV ?

does the TERM value returned match 'echo $TERM' in both environments ?

have you compared the result of the command 'stty -a'  in both environments ?

if you could post the outputs to the above that would be very helpful if you require any further direction.


 
12.04.2007 at 01:07PM PST, ID: 20406497
JJSmith:

sorry forgot to add, please prefix the 'tset' command with 'eval' ie:

eval  `tset -s `

specifically dealing with your backspace problem you could use:

stty erase <Press your backspace>

but ideally you would want this in your .profile or even better the default /etc/profile when your terminal type has been correctly identified.
