You won't be able to use the parallel port without some extra hardware, namely a parallel to serial converter. It would make a lot more sense to use the serial port. > I have a null modem cable, a IIgs to Modem cable with hardware handshaking > (Alltech Electronics part number CAB006R), a IIgs to Modem cable (Alltech > Electronics part number CAB007), and a RS-232 wiring adapter but more > parts could be purchased. I don't know the precise pinout of any of these cables - the flow control lines could be implemented in a variety of ways, so it is probably easiest to specify the cable pinout you should be using. You can probably rig one up from this. First, for those who came in late, here is the pin numbering of the Mini-Din-8 that I'm using, which matches Apple's diagram in the IIgs Owner's Guide. The following picture is looking into the socket on the printer, or into the back of the Mini-Din-8 plug on the cable. 8 7 6 5 4 3 2 1 IWII (Mini-Din-8) PC (DB-25F or DE-9F) 1 HShkOut ------ CTS 5 8 2 HShkIn ------ DTR 20 4 3 TxD- ------ RxD 3 2 4 Gnd ------ Gnd 7 5 5 RxD- ------ TxD 2 3 6 TxD+ (not connected) 7 (unused) (not connected) 8 RxD+ ------ Gnd 7 5 I'm assuming that the PC doesn't care about the state of its DSR flow control input when talking to a printer. If it needs DSR active, then you should connect IWII pin 1 (HShkOut) to both pins 5 and 6 on the PC for a DB-25F, or pins 8 and 6 for a DE-9F. -- David Empson dempson@actrix.gen.nz Snail mail: P.O.
