- The light pen port is just that, a light pen port. Most CGA video
- adapters have one, though they arn't used much anymore. I don't know
- the pinout of the 9-pin DB connector, On normal CGA card there is only
- a 6 pin connector:
- 1 -Light pen input
- 2 KEY (NOT USED)
- 3 -Light pen switch
- 4 Chassis ground
- 5 +5Vdc
- 6 +12Vdc
-
- I can't see anyway this could be used as a serial port :( ,it doesn't
- even have any data outs so I think it would be impossible.
