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? Aki. -- / Phone: 408-662 9664 Fax: 662 9676 | "Aki" pronounced: Ah-Key.
