The modem cable plugged into the telephone icon port on the IIgs goes to
a NULL modem connector which goes to a modem cable connected to the PC COM-1
or COM-2 port. No actual modem is required.
The NULL modem connector is just an adaptor or cable which swaps around
Transmit and Receive lines plus a few control lines. Each computer running a
telecom terminal 'thinks' the other computer is a modem.
