terminal displays garbage when switching screens

[Richard Darling]

One of our applications uses vt220 emulation (text only). Intermittently when users switch screens the terminal swicthes to the alternate character set like the command tput smacs had been entered. Our second application uses wyse60 emulation and there is no problem. The repsponse center and our vendor have not been able to figure it out. The first time it happened we were upgrading from 9.04 to 10.20 on a g40, and it has been happening ever since. I recently upgraded to an L1000 running 11.00, and I hoped that the problem wouldf go away; it didn't. It happens about 4 - 5 times per day in a user base of 50.

Richard:

Sounds like the application is doing screen postioning and/or highlighting with 'tput' commands. Issuing 'stty sane' will probably correct the problem, although that doesn't address the root cause.

Hi
What is the default emulation of the terminal?
If it is wy60 then that could point to the terminal dropping fron vt220 to its default,

Whereas in wy60 mode it has nowhere to go.

Paula, the users are using Powerterm emulation from a PC network, and the terminal is set to vt220. I verified the terminal setting with echo $TERM.

Hi
JUST A THOUGHT.

Have you upgraded the Win OS as I have had problems with Win 2000 and Hostaccess.
