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.
<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.
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.
Command: +FRS=?
Response: +FRS: <time> range
Example: +FRS: 0-255
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.
<mod> Decimal number corresponding to the selected modulation mode and
data rates shown in Table 2-2.

CONNECT Reported when the modems begins the training sequence after
receipt of a valid <mod> value.
ERROR If the modem's transmit buffer becomes empty and the last
transmitted character is NUL (00), the modem continues to transmit NULs
until the DTE sends more data or five seconds elapses. After five seconds
elapse with an empty transmit buffer, the modem will turn off the transmit
carrier, return to the command state, and report the ERROR result code.
OK If the modem's transmit buffer becomes empty and the last transmitted
character is not NUL, the modem will turn off the transmit carrier, return to the
command state, and report the OK result code.
