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.
Reporting Current or Selected Values
Command: +FTM?
Response: +FTM: <mod>
Example: +FTM: 98 For V.17 9600 bps.
Reporting Supported Range of Parameter Values
Command: +FTM=?
Response: +FTM: (<mod> range)
Example: +FTM: 3,24,48,72,73,74,96,97,98,121,122,145,146
+FRM - Receive Facsimile
This command causes the modem to enter the receiver mode using the modulation defined below.
Syntax
+FRM=<mod>
Defined Values
<mod> Decimal number corresponding to the selected modulation mode
and data rates shown in Table 4-2.
Reporting Current or Selected Values
Command: +FRM?
Response: +FRM: <mod>
Example: +FRM: 98 For V.17 9600 bps.
Reporting Supported Range of Parameter Values
Command: +FRM=?
Response: +FRM: (<mod> range)
Example: +FRM: 3,24,48,72,73,74,96,97,98,121,122,145,146
Result Codes
CONNECT Reported when the selected carrier is detected.
+FCERROR Reported if another carrier is detected and FAR=0; the modem
then returns to the command state.
NO CARRIER Reported if loss-of-carrier is detected.
OK Reported if the DTE sends any character to the modem other than
XON or XOFF while operating in configured flow control from the
DTE; the modem then returns to the command state.
+FTH - Transmit Data with HDLC Framing
