See the doc for that driver for details. I can speak for NANSI.SYS and NNANSI.SYS - for most cards you can set any mode via escape sequences. In particular, any card that can change modes using the dos standard INT 10H call with AH=0 and AL=mode can be changed with the sequence <escape>[=mh where "m" is the ASCII decimal value for the mode. >If you have >MSDOS 5.0, it's even easier. All you do is type MODE CON: 80 50. :-) The syntax is "MODE CON: cols=80 lines=50", and you can do this with MSDOS 4.0 as well. But you need to use either the DOS supplied ANSI.SYS or an ANSI.SYS clone that is "DOS 4.0 or greater aware". I know that my latest NNANSI.SYS release (5/91, appearing in comp.sources.ibm.pc real soon) works. -- Tom Almy toma@sail.labs.tek.com Standard Disclaimers Apply
