From Apple TIL ( I lost the number)
The two serial ports used on Macintosh computers since the Macintosh
Plus are
       RS-422 mini-circular 8 pin connectors:
       Pin Signal
       1 - HSKo (Data Terminal Ready)
       2 - HSKi (Clear To Send)
       3 - TxD- (Transmit Data -)
       4 - GND (Ground)
       5 - RxD- (Receive Data -)
       6 - TxD+ (Transmit Data +)
       7 - GPi (General-Purpose input); connected to SCC Data Carrier
       		 Detect (or to Receive/Transmit Clock if the VIA1 SYNC signal
       		 is high). Not connected on the Macintosh Plus, Classic,
       		 Classic II, LC, LC II, or IIsi.
       8 - RxD+ (Receive Data +)  The space is between pin 4 and 5

The following are the GeoPort Telecom Adapter Mini-DIN 9 pin assignments:
 (where they differ from Mini-DIN 8 pin )

       What are the pinouts for the mini circular 8 serial ports on the
Macintosh
       Plus and later?

       8 - RxD+ (Receive Data +)
       Looking at the end of a MALE mini-circular connector, the pins are:
       6 7 8                       6 7 8
       3 4 5 The space is          3 4 9 5
        1 2  between pin 4 and 5    1 2
