As Andrew already advised, I also advise you to re-run faxaddmodem and 
choose 1 or 1.0 this time.

The +FCERROR response only belongs in Class 1/1.0.  Its appearance in 
Class 2 is a strong indicator that this modem's Class 2 is broken... in 
probably other ways as well.

Having put this message during the faxaddmodem process... I'm at a loss 
to understand why new users actually pick Class 2.

About fax classes:

The difference between fax classes has to do with how HylaFAX interacts
with the modem and the fax protocol features that are used when sending
or receiving faxes.  One class isn't inherently better than another;
however, one probably will suit a user's needs better than others.

Class 1 relies on HylaFAX to perform the bulk of the fax protocol.
Class 2 relies on the modem to perform the bulk of the fax protocol.
Class 2.0 is similar to Class 2 but may include more features.
Class 1.0 is similar to Class 1 but may add V.34-fax capability.
Class 2.1 is similar to Class 2.0 but adds V.34-fax capability.

HylaFAX generally will have more features when using Class 1/1.0 than
when using most modems' Class 2 or Class 2.0 implementations.  Generally
any problems encountered in Class 1/1.0 can be resolved by modifications
to HylaFAX, but usually any problems encountered in Class 2/2.0/2.1 will
require the modem manufacturer to resolve it.

If you're unsure and your modem supports it, use Class 1.
