Fax Operation
9-2 Modem 3600
Modem Initialization
For fax operation, most fax software packages are equipped with a fax
initialization command string. Entering this command sets the active
profile for fax operation. In some cases certain options should be
modified for particular requirements. The fax software manual provides
information about requirements.
Fax Defaults
Factory defaults, along with the initialization command, support fax
operation. Some initialization commands include the default command
&F and will reissue it for each fax operation. Some fax software
packages do not include the default command, or only issue the default
command when the fax software is first loaded. Subsequent fax
operations may not reset the fax profile and, if a fax required option has
been changed, fax operation will not work.
An example of a fax initialization command is
AT&F V E S0=0
This can be interpreted as:
AT&FReset the active profile to the factory default.
V Set response messages to digit code.
E Disable local echo (off).
S0=0 Disable autoanswer (off).
Fax Autoanswer
Some fax software takes control of autoanswer, disables autoanswer for
the modem, and answers the phone as internally programmed. Other
programs do not control autoanswer at all and require the modem to
have autoanswer enabled. You must check the software manual for the
particular requirements and refer to Chapte r4 for manual/autoanswer
and TALK/DATA selection. Select the necessary options for fax
operation.
