+FTH - Transmit Data With HDLC Framing SELINT 0 / 1 / 2
HDLC protocol and the modulation defined by the parameter <mod>.
Parameter:
<mod> - carrier modulation
3 - V21/300 bps
AT+FTH=? Test command returns all supported values of the parameter <mod>.
Note: test command result is without command echo.
Reference ITU T.31 and TIA/EIA-578-A specifications
3.5.6.2.6 Receive Data With HDLC Framing - +FRH
+FRH - Receive Data With HDLC Framing SELINT 0 / 1 / 2
AT+FRH=<mod> Execution command causes the module to receive facsimile data using
HDLC protocol and the modulation defined by the parameter <mod>.
Parameter:
<mod> - carrier modulation
3 - V21/300 bps
AT+FRH=? Test command returns all supported values of the parameter <mod>.
Note: test command result is without command echo.

3.5.6.3 Serial Port Control
3.5.6.3.1 Select Flow Control Specified By Type - +FLO
+FLO - Select Flow Control Specified By Type SELINT 0 / 1 / 2
AT+FLO=<type> Set command selects the flow control behaviour of the serial port in both
directions: from DTE to DTA and from DTA to DTE.
Parameter:
<type> - flow control option for the data on the serial port
0 - flow control None
1 - flow control Software (XON-XOFF)
2 - flow control Hardware (CTS-RTS) – (factory default)
Note: This command is a shortcut of the +IFC command.
Note: +FLO’s settings are functionally a subset of &K’s ones.
AT+FLO? Read command returns the current value of parameter <type>
Note: If flow control behavior has been set with AT&Kn command
with the parameter that is not allowed by AT+FLO the read
command AT+FLO? will return:
