[comp.sys.apple] Modem Cable

glenn@SLOTH.NCSL.NIST.GOV (G.O.D.s Originator) (12/13/89)

I was wondering if anyone could help me build a cable that 
goes between a Hayes smartmodem and the apple IIGS serial port.
Here are the pinouts:

Hayes Modem								Apple II GS
------------------------------------------------------------

1	Protective Ground					1 Handshake Out (DTR)
2	Transmit Data						2 Handshake In  (DSR)
3	Receive Data						3 Transmit Data Minus
5	Clear to Send						4 Signal Ground
6	Data Set Ready						5 Receive Data Minus
7	Signal Ground						6 Transmit Data Plus
8	Carrier Detect						7 DCD input on SCC
12	High Speed Indicator				8 Receive Data Plus
20	Data Terminal Ready
22	Ring Indicator

------------------------------------------------------------

Anyone have any idea how these match up???


Thanx
