Anyone know the pinout of the 9-pin RS-232 connector found on HP 9000 Series 300 machines? The manuals are unhelpful... tom lane ----- ARPA: lane@ZOG.CS.CMU.EDU UUCP: ...!seismo!zog.cs.cmu.edu!lane BITNET: lane%zog.cs.cmu.edu@cmuccvma

My Configuration Reference Manual says that the pinouts are as follows: DB9 DB25 DTR 1 20 TXD 2 2 RXD 3 3 RTS 4 4 CTS 5 5 DSR 6 6 not implemented GND 7 7 signal ground CD 8 8 RI 9 9 I haven't used it, but if I'm reading the manual right, the interface "looks" like a DTE, so if you're making DB9->DB25 cables, use male DB25 connectors. If you're hooking up a modem, you may need to flip a switch on the card to enable modem control. This interface has only a one-byte buffer and no on-board support for modem handshaking or flow-control, and input at rates above 2400 baud (or above 300 baud concurrent with disk accesses on the builtin hp-ib interface) may result in loss of data.

As of May 16, 1986, the s320 comes with a cable which converts the 9-pin to a standard 25-pin female (like the s310). It's part number is 98561-61604. This is what it does: Name 9-pin 25-pin DTR 1 20 TXD 2 2 RXD 3 3 RTS 4 4 CTS 5 5 DSR 6 6 GND 7 7 DCD 8 8 RING 9 22 PGND shell 1 & shell Perry Scott ..{ihnp4,hplabs}!hpfcla!perry-s
