Hi Joaquin,

A handheld terminal is still just a terminal. Is TERM set correctly? Has the application been changed recently? Do you have other Trakker24xx devices that are working correctly? Is it a specific loginid or any that has the problem? Can you login on the handheld as a non-application user (perhaps your loginid)?

Just some thoughts.

Yes, the telnet connection on handhelds work fine the problem consist in the screen manage may be.The system and trakker emulate vt220 and i test vt100 to. The two trakkers model 24xx has the same problem.


Thanks

Hi again,

What happens if you login on a regular terminal (or emulator window)? I'm assuming the handheld screen is a limited number of lines and columns. Maybe if you try it on a 80x24 vt220 (or vt100) you'll see what's happening.

We use handhelds where an in-house menu is displayed aftrer logging in. At times we've mistakenly made the menu too large for the handheld screen and have had to modify it.

Hi Darrel, the last week the D270 box was runnig UX 10.2 and handhels works fine. I install UX 11.0 using cold installation method to run the new application version that require HP-UX 11.0 and the handhelds dont work.

Thanks

[Darrell Allen]

Well, now it's probably time to go back to the application's installation guide. Something (termcap, terminfo, some environmental variables) is apparantly not set correctly since the cold install of 11.0.

Telnet already is verified. Perhaps you can telnet again and run vi to see if that works.

Hi:

My advice would be to check two things:

1) export TERM=vt220
infocmp > /tmp/vt220
Do this on both 10.20 and 11x and then run diff to compare the terminfo differences. If you like, you can copy the file to the 11x box and do tic < /tmp/vt220 to create a new /usr/lib/terminfo/v/vt220 entry.

2) stty -a < /dev/ttyxxx and make sure that setting match especially values like cs8 istrip iexten opost. Do this on both versions.

Some applications rewrite the terminal definition information to make them work with smaller screen handhelds.

If you were using vt220 on hpux10.20, you might want to untic vt220 from the 10.20 system and then tic that on your 11.00 system as your new vt220.

It is possible their may be some peculiar escape codes for the handheld that make it not quite vt220 compatible.
