Well, I'm not entirely certain as to why implementing
Class1HasRHConnectBug would lead to an increase of the type of session
incidents that you illustrate (although I can think of possibilities),
the HDLC message being received there is a CTC signal.
The snippit there basically means that we sent PPR and expected another
Phase C high-speed data session, but instead a V.21 HDLC carrier was
detected with the CTC signal in it.
As long as the session from there continues properly then HylaFAX's
behavior here should be considered proper. The sender transmitted CTC
out of sequence, and thanks to the modem's +FCERROR support HylaFAX was
able to detect that CTC signal and move on with the session.
I added Class1HasRHConnectBug: yes to both multitech modem config files.
I don't see the FCS error anymore but I get these now.
