Re: 486 PC. Keyboard problem.
I booted another PC from the DOS start up disk and got similar responses to those I described in post #34.
Then I started the same PC in windows XP, pressed the Windows and R keys simultaneously to get a run prompt and entered "CMD" to get a DOS prompt.
Entering "mode" at this prompt returned the full parameters of the port.
So perhaps the "REPLY B" response is a red herring?
