I am trying to find a C or assembler routine that can do timing measured in milliseconds on the PC. The problem is unfortunately the PC system clock is updated only 18.2 times a second, intervals of only 55 milliseconds. I've heard there are routines to do this. I don't know if the the PS/2 line (386 machines) are bound by this limitation but my guess is that they are. If you could help me with this I would appreciate it. You could leave a message or the code at RED6 at PSUVM. Thanks!
