These connectors are the same as they use on the RT for the eight port
expansion box. The part number for the AScii Terminal cable that can be
used on these ports is 6298525 (option number 6298186). But the 
following is the real important info.

pin 1 = TxD
    2 = DTR
    3 = RTS
    4 = 
    5 = 
    6 = RxD
    7 = DSR
    8 = CTS
    9 = CD
    10 = Signal Ground
