AT Commands
Page 169
For example, the command to instruct the modem to automatically answer a data
or fax call and also enable reception is:
AT+FAE=0; +FCR 1 <CR>
Basic data mode and fax service class mode select commands are:
AT+FCLASS=0 <CR> for Data Mode
AT+FCLASS=1 <CR> for Service Class 1 Fax
AT+FCLASS=1.0 <CR> for Service Class 1.0 Fax
AT+FCLASS=2 <CR> for Service Class 2 Fax
In Class 2, the DCE makes and terminates calls, manages the communication
session and negotiates (T.30 protocol) and transports the image date to DTE. The
T.4 protocol management of image data, etc., is done by DTE.
The response to
AT+FCLASS= 0<CR> in Data Mode
or
AT+FCLASS=2<CR> in Service Class 2 Fax
is
OK
The service class may be set by the DTE from the choices available using the
“+FCLASS=<VALUE>” command.
General Rules
1.
+Fnnn commands must be entered completely, otherwise an ERROR
response is sent.
2.
All response messages are preceded and followed by <CR><LF>. Multiple
response commands (e.g., +FDIS: +FCSI: and +FDCS:) will, therefore,
appear to a have a blank line between them.
3.
Fax Class 2 commands can be separated by the “:” character. The “;” character
can be omitted if desired. Non-data commands cannot be separated by the “;”
which is allowed as a dial modifier.
4.
All Class 2 commands are assumed to be the final command on a command
line. Additional characters will be ignored.
5.
An ERROR message will be generated if any of the following conditions
occur:
