The serial ports on my AXPpci33 worked fine for me once I'd gotten
the right connector for the 10-pin motherboard header. This caused
more than a little pain, because it's not the `standard' used on
clones around here, and it wasn't documented properly in the manual
I got. It's supposed to be the `standard Intel pinout.' Try this:
Board Serial
Pin Function Pin
1 DCD 1
2 RX (Serial In) 2
3 TX (Serial Out) 3
4 DTR 4
5 Ground 5
6 DSR 6
7 RTS 7
8 CTS 8
9 RI 9
10 No pin installed
These are, I believe, numbered 1-5 across one row, and 6-10 in the
next.
