I am not sure that anything can be done here. The sender does seem to 
consistently do some weird things (like send the FF FF FF FF FF frames). 
The difference between the successful session and the failed session is 
that the failed session did not properly "hear" PPS after the first CRP 
signal.

HylaFAX+ 5.2.2 behavior here will vary slightly. I would advise you to 
try HylaFAX+ 5.2.2 to see if it improves things at all for you. If not, 
then let me see those logs.

Thanks,

Lee.
