4.2.2.5 +FTM - Transmit Facsimile
This command causes the modem to transmit data using the modulation defined below. When a valid
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=

Result Codes
CONNECT
Reported when the modems begins the training sequence after receipt of a valid
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.
