+FRM - Receive Facsimile
This command causes the modem to enter the receiver mode using the modulation
defined below.
Syntax +FRM=<mod>
Defined Value
<mod> Decimal number corresponding to the selected modulation
mode and data rates shown in Table A-18.
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
This command causes the modem to transmit data using HDLC protocol and the
modulation defined below.
Syntax
+FTH=<mod>
Defined Value
<mod> Decimal number corresponding to the selected modulation
mode and data rates shown in Table A-18.
Result Codes
CONNECT Reported for either of two conditions:
1. At the beginning of transmission of the training
pattern for the selected 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 transmitting 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.
