Transmit Data. +FTM=n causes the modem to transmit data using
the modulation defined below. An ERROR response code results if
this command is issued while the modem is on-hook.
+FTM=24 V.27 ter 2400 bps
+FTM=48 V.27 ter 4800 bps
+FTM=72 V.29 7200 bps
+FTM=96 V.29 9600 bps
Receive Data. +FRM=n causes the modem to enter the receiver
mode using the modulation defined below. An ERROR response
code results if this command is issued while the modem is
on-hook.
+FRM=24 V.27 ter 2400 bps
+FRM=48 V.27 ter 4800 bps
+FRM=72 V.29 7200 bps (Not supported(1))
+FRM=96 V.29 9600 bps (Not supported(1))
Transmit Data with HDLC Framing. +FTH=n causes the modem to
transmit data framed in HDLC protocol using the modulation
defined below. An ERROR response code results if this command
is issued while the modem is on-hook.
+FTH=3 V.21 Channel 2300 bps
Receive Data with HDLC Framing. +FRH=n causes the modem to
receive frames in HDLC protocol using the modulation defined
below. An ERROR response code results if the command is issued
while the modem is on-hook.
+FRH=3 V.21 Channel 2300 bps
Receive Test Data. +FRTn causes the modem to go off-hook and
begin demodulating received data at the specified rate.

Transmit Test Data. +FTTn = m causes the modem to transmit a
continuous test pattern at the specified rate. The transmission will
terminate by a DTE abort (i.e., any character recognized at the DTE
interface).
