AT Commands

Response: +FTS: <time> range
Example: +FTS: 0-255
+FRS - Receive Silence
This command causes the modem to listen and report an OK result code when
silence has been detected on the line for the specified period of time. This
command will terminate when the required period of silence is detected or when
the DTE sends the modem another character other than XON or XOFF, which is
discarded. In either event, the OK result code is returned.
This command is aborted if any character is received from the DTE after receipt of
the command but before the time delay elapses. In this case, the modem discards
the aborting character and issues an OK result code.
Syntax +FRS =<time>
Defined Value
<time> Decimal number from 0 (default) to 255 which specifies the
length of time in 10-ms intervals to delay before responding
with the OK result code after detecting silence on the line.
Result Codes
OK Reported when silence has been present on the line for the
specified amount of time or when the DTE sends the modem a
character other than XON or XOFF.
ERROR <value> is invalid or this command is issued while the modem
is on-hook.
Reporting Supported Range of Parameter Values
Command:
+FRS=?
Response: +FRS: <time> range
Example: +FRS: 0-255
+FTM – Transmit Facsimile
This command causes the modem to transmit data using the modulation defined
below. When a valid <mod> value is entered, the modem transmits the proper
training sequence in the selected mode, followed by constant 1 bits until data is
received from the DTE. The modem also returns the CONNECT result code at
the beginning of the training sequence.
Syntax +FTM=<mod>
Defined Value
<mod> Decimal number corresponding to the selected modulation
mode and data rates shown in Table A-19.
