Every Apple Super Serial Card and compatible that use DB25's support full
hardware handshaking. I have personally verified this one both an Apple
SSC (too expensive) and an AST Envoy (which I have in my ][+ now). If your
serial card does not support the modem controls (DTR, DTE, RTS, CTS, etc.)
then you have been gipped.

However, your modem software must also support them and that may be a problem.
The IIGS modem port supports them, I believe proterm does (not sure), and
I don't know about kermit.
