Default Re: 486 PC. Keyboard problem.

Alas no serial printer, it's quite possible the machine never had one.

However I could run the hyperterminal program on another PC and send characters to it as you suggest.

The problem may be more fundamental than a com port problem though. The back up battery on the machine's control card has leaked dissolving the tracks to its com port. This is quite a common problem. Ironically the battery doesn't actually do anything in this application.

Fortunately I have a spare control card taken from another machine which was upgraded to use a USB port. Further testing will have to wait until next week though.
