Fax Operation
9-8 Modem 3600
The Modem 3600 returns an ERROR result code if any of the above
commands are issued while the modem is on hook.
Facsimile Transmit +FTM=(Mod)
+FTM=(Mod) causes the modem to transmit data using the modulation
and speed selected with the (Mod) parameter. For V.27 ter, V.29, and
V.17 modulations, the modem first transmits the required training
sequence (with echo protector tone). After it is appropriately configured
for transmission, the modem returns the CONNECT result code and
transmits constant 1 bits until data is received from the DTE. For
additional information, consult the Class 1 specification.
Facsimile Receive +FRM=(Mod)
+FRM=(Mod) causes the modem to receive data using the modulation
and speed selected with the (Mod) parameter. If the selected carrier is
detected, a CONNECT result code is sent to the DTE; if a different
signal is detected, the modem sends a +FCERROR (CONNECT
ERROR) result code and returns to command mode. This command is
aborted if the DTE sends any character to the modem other than DC1 or
DC3 during this mode. For additional information, consult the Class 1
specification.
