Unfortunately, there is no universal mechanism for detecting what kind of terminal you're attached to. Even worse, you can't try to "autodetect" it, since some terminals (now thankfully rare) will do Bad Things(tm) like lock up when they're prodded in the wrong way. Just look through /etc/termcap sometime, it's "fascinating" reading... ;) There is, however, an escape sequence pair you can use to determine what model of VTxxx you're talking to. It's documented rather nicely in ctlseqs.ms, which is in /usr/share/xterm/doc/, so I won't waste bandwidth by detailing it here. I'd tend to say that assuming VT100 until told otherwise by the user isn't a bad idea. In fact, you can probably get away with assuming VT102. [I had the opportunity several years to get very well-acquainted with not only all the VT1xx escape sequences but all the bugs you have to emulate, too, while writing a VT100 emulator in Turbo Pascal - even Telix was too slow on my XT...] -- Jeffrey Sean Connell __ | VP of Software Development, Convergence Equipment [EMAIL PROTECTED] \/ | PGP key: http://www.canuck.gen.nz/~ankh/pgpkey.html ------------------------+----------------------------------------------------
