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.
