I tried 9600 as well without any luck. I think it is
the cable, I *always*
have trouble with serial cables. At the moment I have a cable with pins 2
and 3 crossed over and pins 7 and 8 on the PC side shorted together. I may
have to crack open my breakout box to sort this out.
That doesn't sound right. I can not remember if the Ultra 5 has a DE9
or DB25 socket on the back.
Anyway. Pins 2 and 3 are the TX and RX pins (not respectively) on both
DE9 and DB25. Pin 5 on the DE9 is GND, as is pin 7 on the DB25. If you
are running windows you may need additional pins shorted together but
I seem to recall that most recent offerings from Microsoft can be
configured to work with just the three wires.
Good luck.
