Chapter 6 – Fax Class 1 and Class 1.0 Commands
Multi-Tech Systems, Inc. SocketModem MT5600SMI Developer’s Guide 92
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
Command: +FRM Receive Facsimile
Description: This command causes the modem to enter the receiver mode using the
modulation defined below.
Defined Values: <mod> Decimal number corresponding to the selected modulation m ode and
data rates shown in Table 6-2.
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.
Command: FTH Transmit Data with HDLC Framing
Description: This command causes the modem to transmit data using HDLC protocol and
the modulation defined below.
Defined Values: <mod> Decimal number corresponding to the selected modulation m ode and
data rates shown in Table 6-2.
Result Codes: CONNECT Reported for either of two conditions:
1. At the beginning of transmission of the training pattern for the se lected
modulation.
2. If the Final Frame bit is 0.
OK Reported for either of two conditions:
1. If the Final Frame Bit is 1.
2. if the DTE sends only <DLE><ETX> (a null frame) while transm itting flags.
ERROR Reported if five seconds elapse from the time when the modem
reported the CONNECT result code without any additional data transmitted
from the DTE; the modem then turns off carrier and returns to the command
mode.
Reporting Current or Selected Values:
Command: +FTH?
Response: +FTH: <mod>
Example: +FTH: 98 For V.17 9600 bps.
Reporting Supported Range of Parameter Values:
Command: +FTH?
Response: +FTH?
Example: +FTH: 98 For V.17 9600 bps.
