+FTS - Stop Transmission And Pause

SELINT 0 / 1 / 2

<time> - duration of the pause, expressed in 10ms intervals.
0..255

AT+FTS=?

Test command returns all supported values of the parameter <time>.

Note: test command result is without command echo

3.5.6.2.2 Wait For Receive Silence - +FRS

+FRS - Wait For Receive Silence

SELINT 0 / 1 / 2

AT+FRS=<time>

Execution command causes the modem to listen and report OK when
silence has been detected for the specified period of time. This command
will terminate when the required silence period is detected or when the DTE
sends another character other than XON or XOFF.

Parameter:
<time> - amount of time, expressed in 10ms intervals.
..0..255

AT+FRS=?

Test command returns all supported values of the parameter <time>.

Note: test command result is without command echo.

3.5.6.2.3 Transmit Data Modulation - +FTM

+FTM - Transmit Data Modulation

SELINT 0 / 1

AT+FTM=<mod>

Execution command causes the module to transmit facsimile data using the
modulation defined by the parameter <mod>.

Parameter:
<mod> - carrier modulation
24 - V27ter/2400 bps
48 - V27ter/4800 bps
72 - V29/7200 bps
96 - V29/9600 bps

AT+FTM=?

Test command returns all supported values of the parameter <mod>.

Note: the output is not bracketed and without command echo.
