In Greg Schaefer's ProTERM v3.0 manual, the suggested wiring for an Apple
IIgs/IIc+ modem cable is (and it works -- I got ranges of 2690-3264 cps
downloading textfiles from the Hayes BBS with an Intel 14.4ex): 


Computer Port           Modem           Signal Name
(Male MINI DIN-8)       (Male DB25)
3                       2               TD (transmit data)
5                       3               RD (receive data)
4                       7               GND (signal ground)
Short 8 to 4                            GND (signal ground)
2                       5               CTS (clear to send)
1                       4               RTS (ready to send)
                        Short 4 to 20   DTR (data terminal ready)
7                       8               DCD (data carrier detect)

NOTE: This cable requires that "short circuits" be placed in the cable. This
consists of creating a "Y" connection between the three pins. On the MINI
DIN-8 end, pins 4 and 8 should be connected to each other as well as to pin 
7 of the DB25. On the DB 25 end, pins 4 and 20 should be connected to each
other as well as to pin 1 of the MINI DIN-8.
