How do you change the video attributes on an IBM PC. I would like to bold,reverse,underline strings on the screen but don't know how or what escape sequences to use. Can anyone help? Terry Tanski - Systems Analyst Athabasca University Athabasca, Alberta CANADA (!alberta!auvax!terryt)

Send the following sequences for controlling attributes: ^[[0m normal ^[[1m bold ^[[4m underline (on monochrome cards) ^[[5m blink ^[[7m reverse Experiment with: ^[[30m - ^[[37m and ^[[40m - ^[[47m for a variety of foreground and background colors. Note that using the ANSI driver is very slow -- adequate for very simple programs, but not for a commercial product. Clayton E. Cramer

First you must have device=ansi.sys in your config.sys file and of course have ansi.sys available. ANSI.SYS should be on your MS-DOS diskette. The following is an incomplete set of ANSI sequence's : ESC code sequence Function ----------------- -------- Erase Functions: ESC[2J Clear screen and home cursor ESC[K clear to end of line Set graphics rendition: ESC[#;#;...;#m Set display attributes where # is 0 for normal display 1 for bold on 4 underline (mono only) 5 blink on 8 invisible 30 black foreground 31 red foreground 32 green foreground 33 yellow foreground 34 blue foreground 35 magenta foreground 36 cyan foreground 37 white foreground 40 - 47 background colors in same order as above foreground ESC[=#;7h Put screen in mode # 0 for 40 x 25 mono 2 for 80 x 25 mono This is no where near all of them but maybe it's a start. Hope it helps. Lynn Barbee Bell Communications Research GSP to Univ. Of Virginia

True enough, but there are public domain replacements for the ANSI driver that are very fast, and quite adequate for commercial products. The two I know about are NANSI.SYS (my favorite :-) and the recently posted QWIKANSI.SYS. If your application sets RAW mode on the console fd (this is done with the IOCTL system call) and uses NANSI, plain old puts and printf statements run ten times faster than before. -- Dan Kegel srs!dan@cs.rochester.edu dan%srs.uucp@cs.rochester.edu rochester!srs!dan
