It started all two days ago, when the mouse cursor begun to stutter and occasionally freeze, but then it worked again. Yesterday, the port stopped working for good: even though it's properly recognized by Windows, anything you connect (and I only have serial mice) won't be detected. The same issue happens in Linux so it's definitely an hardware issue, most likely a bad port. I have disabled it and I'm using the mouse on the COM2 port, after reprogramming it in BIOS to use the IRQ from the dead port.
Last time I had a com port problem it was some weird issue with BIOS corruption. The onboard hardware apparently barfed, so was disabled, whereupon an ISA i/o was used at standard addresses and the same problem persisted. Forgot how the BIOS chip got fingered, but I think it was a checksum error or something. Obtained right bios update for board, tried reflashing, but flashes gave errors. ... think I gave up on it, having other fish to fry, next move would have been fresh chip flashed in another machine. Cannot remember anything more specific or utils used, too long ago.
