- You know, the BIOS communications functions aren't very good.
- In fact, if I were you, I'd use a FOSSIL driver and check its
- documentation, or alternatively write routines that access
- the UART directly. (I did it once in C but got troubles with
- speed; writing them in assembler should be fast enough.)
-
- Also, in case you haven't tried, I recommend checking out
- a database called HelpPC. Probably available at your local
- BBS and/or nic.funet.fi & garbo.uwasa.fi.
-
- Sorry for not being able to help with your original problem.
