Sets the current FCLASS to <argument>.
AT+FCLASS=<argument>
0, 1, or 2.0
None.
On the external form factor the ARQ/FAX LED flashes when +FCLASS is set to 1.
None.
None.
Returns the current FCLASS, 0, 1, or 2.0.
AT+FCLASS?
None.
None.
None.
None.
None.
Returns the possible values of FCLASS.
AT+FCLASS=?

None.
This command causes the modem to stop any transmission. The modem then waits for the specified amount of time, and then sends the OK result code to the DTE. The value <time> is in 10 millisecond intervals and has limits of 0 to 255.
AT+FTS=<time>
0-255
None.
None.
None.
None.
Causes the modem to listen, and to report back an OK result code when silence has been present on the line for the amount of time specified. The value <time> is in 10 millisecond intervals and has limits of 0 to 255. The command will terminate when the required amount of silence on the line is detected or the DTE sends the modem another character, which is discarded. In either event, the OK result code will be returned to the DTE.
AT+FRS=<time>
0-255
None.
None.
Any character sent from the DTE to the modem will abort the wait. The modem will then return an OK result code to the DTE.
None.
Causes the modem to transmit data using the modulation selected with the <mod> parameter. Table 2 lists all possible values for the <mod> parameter.
The modem returns the CONNECT result code and transmits the proper training sequence in the selected mode, followed by constant 1 bits, until data is received from the DTE.
AT+FTM=<mod>
3, 24, 48, 72, 96, 97, 98, 121, 122, 145, 146
The modem will filter transparent commands, <DLE><char>, as specified in EIA/TIA578.
None.
The modem will abort when it receives a <DLE><ETX> character from the DTE.
None.
Causes the modem to enter receive mode using the modulation specified in table 2.
When the selected carrier is detected, the modem will send the CONNECT result code to the DTE. If a different signal is detected, the modem shall send a +FCERROR (Connect Error) result code to the DTE, and return to command state.
AT+FRM=<mod>
3, 24, 48, 72, 96, 97, 98, 121, 122, 145, 146
The modem will filter transparent commands, <DLE><char>, as specified in EIA/TIA578.
None.
Loss of carrier will abort +FRM and cause the modem to return a NO CARRIER result code.
None.
Causes the modem to transmit data framed in HDLC protocol using the modulation mode selected. The values for the <mod> parameter are listed in table 2.
The modem will send the CONNECT result code to the DTE, and transmit signal converter training (if required) followed by flags until the first byte of data is sent by the DTE.
AT+FTH=<mod>
3, 24, 48, 72, 96, 97, 98, 121, 122, 145, 146
The modem DTE interface is specified in EIA/TIA578.
None.
None.
None.
Causes the modem to receive HDLC framed data using the modulation specified by <mod> and deliver the next frame to the DTE.
If the modem detects the selected carrier with an HDLC flag, the modem shall send the CONNECT result code to the DTE. If a different signal is detected, the modem shall send +FCERROR (Connect Error) result code to the DTE and return to command state. The modem will return to command state upon loss of carrier, sending the NO CARRIER result code to the DTE.
AT+FRH=<mod>
3, 24, 48, 72, 96, 97, 98, 121, 122, 145, 146
The modemDTE interface is specified in EIA/TIA578.
None.
None.
None.
The +FATX command causes the modem to transmit asynchronously using the modulation specified by <mod>.
AT+FATX=<mod>
3, 24, 48, 72, 96, 97, 98, 121, 122, 145, 146
The modem DTE interface is specified in EIA/TIA578.
None.
None.
None.
The +FARX command causes the modem to receive asynchronously using the modulation specified by <mod>.
AT+FARX=<argument>
3, 24, 48, 72, 96, 97, 98, 121, 122, 145, 146
The modem DTE interface is specified in EIA/TIA578.
None.
None.
None.
