If you believe that your modem conforms to the Class 1, Class 2, or

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.

There is no prototype configuration file for your modem, so we will
have to fill in the appropriate parameters by hand.  You will need the
manual for how to program your modem to do this task.  In case you are
uncertain of the meaning of a configuration parameter you should
consult the config(@MANNUM4_5@) manual page for an explanation.

Note that modem commands must be specified exactly as they are to be
sent to the modem.  Note also that quote marks (") will not be displayed
and will automatically be deleted.  You can use this facility to supply
null parameters as "".

Finally, beware that the set of parameters is long.  If you prefer to
use your favorite editor instead of this script you should fill things
in here as best you can and then edit the configuration file

"$CONFIG"

after completing this procedure.
