- The problem that I reported earlier with a PC/XT's serial port
- screwing up memory and freezing my program; is now solved.

- All I had to throw out was a little error that did not surface
- anywhere else: a write to the Modem Status Register (value 0).
-
- Has anyone else experienced something similar, where an innocent
- OUT to a well known "safe" address corrupts the PC?
