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
4.2.1.5 +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 Values
<mod> Decimal number corresponding to the selected modulation mode and data rates
shown in Table
4-2.

Result Codes
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 a 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
was not NUL,
the modem will turn off the transmit carrier, return to the command state, and report the
OK result
code.
