You've sent us the receive-side log.  How about sending us the send-side 
log, too?

This sequence of commands occurs because the modem detects the V.21 
carrier when we told it to expect the V.29 carrier.  It indicates a 
dissynchronization between the sender and receiver has occurred.

Recent versions of HylaFAX improve the behavior in this regard - they're 
usually capable of detecting the V.21 signal and act upon it.

However, the rest of your log shows *a lot* of data loss occurring 
between sender and receiver.  My guess is that you need to have your 
phone lines checked... or you're using VoIP.
