If you hit docs.Sun.com, you can likely find a field service manual for this.
As pointed out // are two parallel lines (sun finally offered
a parallel port with the Classic and my years of fighting serial
printers and plotters were over :)
The serial port is the same introduces with the Sparc 5/20, AFAIK.
It's port A and port B in one. Why they didn't just use DIN to
save space, I dunno. But a regular cable will get you the A serial port.
Go to Celeste Stokeley's Serial port page of all knowledge.
(stokely.com) I've made cables for this that grab both ports,
it's just a matter of knowing pinouts. You're not a system
admin until you've made lots of serial cables and then redone
them right :)
I don't think you'll have much modem joy > 38.400 on the built in
ports. Lock the modem to that speed, lock teh serial port to
that speed, let the modem negotiate with the other end.
