AT Commands for CX81801/CX06833/CX81300/CX06827 Modems Reference Manual
102184B Conexant 4-9
+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.
