I recently installed AT+T Unix SysV/386 3.2 and read in the manual how you can change the screen attributes through escape codes. I have no idea how these work, however, and the manual only said that you use the unix escape sequence ([) and then the qualifier. I've tried various ways and none seem to work. Another aspect I'm interested in is changing the background and foreground colors. I'm tired of black and white. Can anyone out there explain how this works? Thanx in advance for any help. -- Jesse W. Asher - Dynasys - (901)382-1705 Internet: jessea@dynasys.UU.NET 6196-1 Macon Rd., Suite 200, Memphis, TN 38134 UUCP: uunet!dynasys!jessea

You can do this from the shell (or your .profile) with the following: echo "\033[XXm" Where XX is the color/attribute specification. See display(7) for a complete list of what colors and/or attributes can be used. While this does work at setting the color attributes, it does not provide a satisfactory implementation because it doesn't cause the entire screen to be colored. Only characters output after that sequence are in the specified color. Another problem is that many programs (like vi) clear the color/attributes by sending an \033[0m at startup time. Most of the time people set thier colors in the shell command prompt so that the colors are set/restored each time the prompt is displayed. -- +-----------------------------------------------------------------------+ | Conor P.

Actually no, programs like vi(1) clear the color/attributes by sending whatever TERMINFO tells them does the trick for your selected terminal! Therein lies the real trick for getting a different colored console: define an alternative AT386 entry with the colors you want specified by twiddling the startup sequences. The underlying AT_ANSI display driver is a generic color terminal that's happy to use whatever colors you ask. This really works; I also use it to run a 43 line console which is the joy of my existence. -- War is like love; it always \%\%\% Tom Neff finds a way. -- Bertold Brecht %\%\%\ tneff@bfmny0.UU.NET

Well if you have Simul-task on a system I found out you can use a dos program to set the pallet and character colors. When it returns to unix they stay that way. All the unix program I run do not reset the color. This works with vga and some pd program I have called vpt. The vpt program does r-g-b color mixing so you can create your own color mixture for the forground and background, save it in a file and call it up. I don't know if this works for ega screens. ---Bob -- Bob Palowoda pacbell!indetech!palowoda *Home of Fiver BBS* login: bbs Home {sun|daisy}!ys2!fiver!palowoda (415)-623-8809 1200/2400 Work {sun|pyramid|decwrl}!megatest!palowoda (415)-623-8806 2400/9600/19200 TB Voice: (415)-623-7495 Public access UNIX XBBS

White-on-blue is much nicer than the standard ega/vga text. The setcolor command in SCO Xenix does just that. Unfortunately, the escape codes this program sends are not understood by the System V/386 console driver. -- Pim Zandbergen domain : pim@cti-software.nl CTI Software BV uucp : uunet!mcsun!hp4nl!ctisbv!pim Laan Copes van Cattenburch 70 phone : +31 70 3542302 2585 GD The Hague, The Netherlands fax : +31 70 3512837

Yeah, that's why I called it a "character cell background" color.

= other color? White-on-blue is much nicer than the standard ega/vga text.
Well, maybe... I was rooting around in the support group's "stockroom" of
fixes (trying to find some info about the 2224 modems), and stumbled across
a "fix" for the display driver which sounds like it will do that. Whether
or not it changes the color past the edges of the 25x80 screen I don't know.
Somehow you've gotta convince the NJ hotline to escalate the problem to Lisle
and then "inform" the support consultant of the fix. [Boy, is _this_ ever
gonna get me in trouble!!!]
A caveat: it doesn't look like it has been sent out, so maybe they're
sitting on it for some good reason. (Then again, it looks like it's about
a year old...)
