Its doubtful that ModemWorks (which ProLine uses) would be able to work
with this configuration because ModemWorks uses the Extended Firmware
routines in the Apple IIGS's serial interface.  You'd basically have to
rewrite the ROMs to do this.  On the other hand, I've not heard of any
ModemWorks-based systems having any trouble with hardware flow control.

This may be because the IIGS firmware uses the CTS transition interrupt
rather than polling the CTS signal as do many programs that go right
to the metal in dealing with the 8530 directly.
