Fax Operation
9-6 V.3600
If the DTE sends a character while executing the answer command and
before CED is completed, the call is released and the modem will send
the
NO CARRIER
result code.
On Hook — H
In fax mode, the
H
command instructs the modem to stop any
transmission and terminate the call by going on hook.
Off Hook — H1
The
H1
command instructs the modem to go off hook. In fax mode, this
might be used when the user has used manual dialing to place a fax call.
In this case, no CNG tones are generated and the initial
+FRH=3
is not
implied; it must be explicitly issued by the software.
Class 0 Operation — +FCLASS=0
Setting the Service Class to 0 with the
+FCLASS=0
command sets the
modem in data mode. This default setting is normally only changed by
software if needed.
Class 1 Operation — +FCLASS=1
Setting the Service Class to 1 with the
+FCLASS=1
command
configures the modem as a Class 1 fax modem. This command is
normally only issued by the fax software if needed. When set, the LCD
displays
FAX CLASS 1 MODE .
Service Class Indication — +FCLASS?
The current Service Class setting can be determined with the
+FCLASS?
command. A 0 response indicates the modem is configured
for data mode while a 1 indicates it is set for fax mode. This information
text is preceded and followed by
<CR><LF>
in addition to being
followed by an appropriate result code response.
Service Class Capabilities — +FCLASS=?
The available Service Classes can be revealed by the
+FCLASS=?
command. The modem responds with the information text 0, 1
(preceded and followed by
<CR><LF>
), indicating that the modem
supports both data communication and Class 1 fax operation.
