Re: [hylafax-users] Error following AT+FDT command

[Lee Howard <faxguy@xxxxxxxxxxxxxxxx>]

I wasn't trying to point out a resolution to the problem, but rather, I 
was trying to point out the correct interpretation of the +FHS:1B 
response coming from the modem.

The interpretation problem may be resolved by Class2UseHex, and if not 
then it would require a "bugfix" to the HylaFAX Class 2 code.  However, 
that would just fix the interpretation problem.  +FHS:1B (failure to 
train) will still occur, thanks to the modem firmware, and so the 
solution for that is to 1) turn to the manufacturer for a fix, 2) switch 
to Class 1, or 3) switch modems.
