Serial cable with null modem connected, 9600bps 8N1 The two serial ports on J1 are usually labelled SIO-A and SIO-B on the back of the machine and appear as /dev/ttya and /dev/ttyb under SunOS. The documented maximum output speed is 19200 bps. All ports are wired DTE and are compatible with both RS-232C and RS-423, using Zilog Z8530A dual UART chips. The pinout of J1 is: 3 TxD-A 14 DTR-A 33 DD-B 4 DB-A 15 DCD-A 34 CTS-B 5 RxD-A 22 DA-A 36 DSR-B 7 RTS-A 24 BSY-A 38 GND-B 8 DD-A 28 TxD-B 39 DTR-B 9 CTS-A 29 DB-B 40 DCD-B 11 DSR-A 30 RxD-B 47 DA-B 13 GND-A 32 RTS-B 49 BSY-B IDPROM is a NS 74S288 (SIG 82s123, MMI 6331, IM5610 (25ns 32 x 8 Tri-State) Bi-Polar Prom) Format 1 Byte Machine Type 1 Byte Ethernet Address 6 Bytes Date 4 Bytes (32-bit long word which contains the number of seconds since January 1, 1970.)
