The short terminal program in the SSC manual does not emulate
any terminal -- it just takes character from the SSC and displays them
on the screen, and it takes characters typed at the keyboard and sends
them out the SSC. I guess you could say it emulates a DUMB terminal.
Regarding compatibility: I am using SOFTERM, which will emulate about
a dozen or so different terminals (I'm using VT100 emulation), and which
also supports a vast number of Apple serial interfaces, 8--column cards,
modems, printer cards, etc. I don't know what it costs currently, I bought
mine about two years ago. The program permits up- and downloading from and to
DOS 3.3, CP/M, and Apple Pascal diskettes, and supports both the XMODEM
protocol as well as a proprietary protocol called SOFTRANS.
The program's main drawback is that it does not support ProDOS -- that is
supposed to come later this year.
I also use Apple ACCESS, published by Apple Computer, which supports only
ProDOS, and the XMODEM protocol.
If you have difficulties getting your SSC/Hayes setup to work, the problem
I have encountered most often is forgetting to set the jumper on the SSC
in the right direction, and/or the two dip switches. The triangle on the jumper needs to point UP, towards the word MODEM, and switches 1-5 and 1-6 should be
ON or CLOSED (which word is printed on the switches depends on the age of your
card, some have ON/OFF, others have CLOSED/OPEN).
Another problem could be the cable -- if your cable is not a Hayes original
cable supplied with the modem, it might be missing some signal which the modem
requires. Unfortunately, the RS-232 standard is not very standard in its
implementations by the various manufacturers of modems and interfaces!
I usually use 25-wire ribbon cable with crimp-on connectors, that
way I can be sure that ALL signals are getting through.

When using a modem with an Apple, one other thing to check is the cable orientation. Apple uses a null modem cable, not a straight rs232 cable. Transmit and receive are reversed. If you have a voltmeter, you can check the cable pin 2 and pin 3. The transmitter will have -12 volts and the receiver will have +.5 or so. The modem and the cable should of course have the opposite results on pin 2 and pin 3.
