COM2 Problem

I have an old 486 that's running DOS 6.2. I use it to run D/Vision Pro 2.2 video editing software. My problem is getting my system to recoginze the serial mouse on COM2. Quite simply, it won't. MSD and Debug tell me that the COM port is active (02F8H) and that there are no interrupt conflicts.

I have tried two different serial mice, at least three different serial cables, and three different controller cards. Each time the same result.

The real kicker is that I have had a working serial mouse on COM2 on this computer in the past.

Anyone have a clue?

ports can go bad! Use a loopback plug and test the port if there are no resource conflicts everything points to port being bad!
