I am sure someone will correct me if I am wrong, could your trouble
be that you set your fax software for V17 (14,400 Baud) to talk to a
Class 3 (9,600 Baud) machine? When the fax protocols, unlike the
modem ones, have no provision to negotiate the communication speed
to the highest common one.
i.e you should dial out using 9,600 Baud unless you know the
receiving kit can handle 14,400 Baud.
