The modulation being used by the sender is apparently not compatible 
with your modems.  Couple that with a modem bug with V.21 HDLC 
detection,  and you get this.

The +FCERROR responses means that although the modem trained on the 
sender's TCF signal, the modem isn't able to train on the Phase C 
signal, and furthermore is a mess because the +FCERROR indication seems 
to lead one to believe that V.21 HDLC is there - but it's not - yet the 
modem happily thinks so and fouls up the recovery procedure with its 
complications.

I suspect that you're looking at a compatibility problem between the 
sender and your modem.  Given the other misbehaviors that your 
RocketModem is making, chances are good that the culprit here is the 
RocketModem, and you'd probably not have this problem with a different 
modem.  That said, it could be the sender's fault, too.

Thanks,

Lee.
