That isn't a meaningful question. A "null modem" cable only makes
sense when both connectors have two alternative pin arrangements. The
Mini-Din-8 connector on Apple computers and peripherals always has the
same pinout.
The Super Serial Card should be configured to talk to a printer/terminal.
The appropriate cable to use is the same as a cable which connects a
Macintosh or IIgs to a modem (using DSR/DTR flow control).
Mini Din 8 DB-25 male
1 HShk Out 20 DTR (flow control into SSC)
2 HShk In 6 DSR (flow control from SSC)
3 TxD- 2 TxD (receive data into SSC)
4 Ground 7 Ground
5 RxD- 3 RxD (transmit data from SSC)
6 TxD+ (not connected)
7 n.c. (not connected)
8 RxD+ (connect to ground - pin 7 at DB-25, or pin 4 at Mini Din 8)
