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 modi-
fied 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. Users must be aware that
some fax software packages do not include the default command or only
issue the default command when the fax software is first loaded. Subse-
quent fax operations may not reset the fax profile and if a fax required
option has been changed by the user 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&F Reset 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. The user must check the software manual for
the particular requirements and refer to Chapter 4 for manual/autoan-
swer and TALK/DATA selection. Select the necessary options for fax
operation.
