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

= From: cpcahil@virtech.uucp (Conor P. Cahill) = You can do this from the shell (or your .profile) with the following: = echo "\033[XXm" And if you want to be more device independant, try using "tput" when your TERM variable is set to "AT386", instead of "AT386-M" . Like this: TERM=AT386 export TERM tput setb 3 # set character cell background to color 3 tput setf 4 # set character cell foreground to color 4 And here's a handy one: tput clear # clear the screen, home to upper left With luck, two years from now, these will still work on your 2000x2000, 1024 color display, and you won't have to remember the escape sequences for it! :-) Mike Hall att!cuuxb!migh
