[REPOST] Terminal emulation and GNU screen

[sorry for the repost but I can’t see OP on the server]

hi there,
while looking for a replacement for ditto on QNX6.3 I’ve tried (and
discovered) GNU screen.

functionnalities looks very good to me but I am unable to manage to
have a good display on terminal emulation.
most of our application run in character mode and while it looks good
in the console, everythings goes wrong as soon as I launch screen.
May I have forgotten something ? How do I manage to render QNX graphic
character on a vt100 ?

thanks for your help.
