Hey Paul. I took notes when I wired mine. Here are the notes with pictures of my card below.

I THINK I wired both of my ports for RS-232 hardware handshake but did not connect the hardware handshake wires for port 0 that would keep the card from working without hardware handshaking. Basically, the hardware handshaking is disabled with an easy way of adding it in the future.

You should be able to use the pictures of the DB25 connector on one end and the molex on the other to figure out how I wired it. The ribbon cable is junk.

Basic Tx/Rx/Gnd Serial Configuration:
D3 to I4 - Port 0 Receive
I3 to S1-7 - Port 0 Receive
D5 to N4 - Port 0 Transmit
N3 to S1-8 - Port 0 Transmit
S1-4 to S1-10 - Port 0 Ground

E3 to J1 - Port 1 Receive
J2 to S2-7 - Port 1 Receive
E5 to N6 - Port 1 Transmit
N5 to S2-8 - Port 1 Transmit
S2-4 to S2-10 - Port 1 Ground

Hardware Handshake:

D2 to I7 - Port 0 Clear to Send (D2 end NOT connected)
I8 to S1-1 - Port 0 Clear to Send
D1 to I5 - Port 0 Data Carrier Detect (D1 end NOT connected)
I6 to S1-2 - Port 0 Data Carrier Detect
D4 to N2 - Port 0 Request to Send
N1 to S1-3 - Port 0 Request to Send

E2 to I2 - Port 1 Clear to Send
I1 to S2-1 - Port 1 Clear to Send
E1 to J3 - Port 1 Data Carrier Detect
J4 to S2-2 - Port 1 Data Carrier Detect
E4 to N8 - Port 1 Request to Send
N7 to S2-3 - Port 1 Request to Send

These are big pictures, so hopefully no one with a modem will try to load the page.
