printer hanging off an X-station 120

[david lee]

Leaning over my X-station model 120, I see a pair of 25 pin D-shell
connectors. The X-station manual says that one is a serial port,
and the other is a parallel port. That's fine. I can make up a cable
for my printer, but how do I access these ports from AIX ?
Can I do this? And while we're at it, may I access these ports from
my C programs, for data acquisition and such?
Thanks,
