	Hi randrx1, Terminal setup on Unix/Linux is a pain! Basically, there's a terminfo file that contains tables for each terminal type. It looks like you're trying to use a term type of "wyse50" and it's not set up correctly. Fixing the terminfo table is almost a black art. It's difficult to find anyone who knows how to do it anymore. To make matters worse, Universe seems to have it's own terminfo file in the UV folder. I don't know how to fix a terminfo table and I don't know anyone else who knows. Luckily for me, I was able to work around the problem by finding a terminfo record that works correctly with AccuTerm - as long as AccuTerm is running in Wyse 60 mode. I'm emailing you two items. The first - wy60.src -is the terminfo source file. There's a Unix command that will compile it but I don't remember what it is. The second file is the compiled terminal table. All you should have to do is copy the second item (wy60) to your \UV\terminfo\w folder. After that, set your term type to wy60. Hopefully, that will get you running.
