Anybody know of a way to expand the BIOS keyboard buffer in PC-DOS? The 15 key maximum gets frustrating sometimes. I've tried changing the buffer pointers that reside at 40:1a, 40:1c, 40:80 and 40:82 (if my memory is correct) so that they point to an area of memory at 40:90 to 40:F0. This area *appears* to be unused according to the DOS BIOS listings. The change makes the buffer about 40 keystrokes long, and it seems to work great. However, after a *long* time (i.e., 1/2 hour of typing) the system decides that its tired of using the new buffer and enters the Twilight Zone. Any suggestions? G. P. Seaburg Engineering Psych.
