Subject: Geneva pinouts

Again I will send this both to the questioner and the board. I cannot help
you with a source of a suitable cable, but I can supply the pin-outs and in
the unlikely event of there being no source of a suitable plug in the entire
US of A, I have a spare I could mail you (for Christmas!)
The pin-outs:

Serial (not RS232):
1. Ground
2. Transmit data (PTX)
3. Receive data (PRX)
4. RTS
5.C CTS
6. PIN (status ready)
7. POUT (control signal)
8. -
E. Frame ground

RS232:
1. GND
2. TxD
3. RxD
4. RTS
5. CTS
6. DSR
7. DTR
8. DCD
E. Frame ground

the middle row of pins on the connector are not symmetric so you can tell
which way the number goes:

    1   2
   3 4   5
    6 7 8

I hope this helps.
