+IFC - DTE-Modem Local Flow Control
SELINT 0 / 1 / 2
AT+IFC=?
Test command returns all supported values of the parameters <by_te>
and <by_ta>.
Reference V25ter
3.5.3.2.14 DTE-Modem Local Rate Reporting - +ILRR
+ILRR - DTE-Modem Local Rate Reporting
SELINT 0 / 1 / 2
AT+ILRR=<n>
Set command controls whether or not the +ILRR: <rate> information text is
transmitted from the modem (module) to the DTE.
Parameter:
<n>
0 - local port speed rate reporting disabled (factory default)
1 - local port speed rate reporting enabled
Note: If AT+IPR=0 (in autobauding) local port speed reported will be 0.
Note: this information if enabled is sent upon connection.
AT+ILRR?
Read command returns active setting of <n>.
AT+ILRR=?
Test command returns all supported values of the parameter <n>

3.5.3.2.15 DTE-Modem Character Framing - +ICF
+ICF - DTE-Modem Character Framing
SELINT 0 / 1 / 2
AT+ICF=<format>
[,<parity>]
Set command defines the asynchronous character framing to be used when
autobauding is disabled.
Parameters:
<format> - determines the number of bits in the data bits, the presence of a
parity bit, and the number of stop bits in the start-stop frame.
0 - autodetection
1 - 8 Data, 2 Stop
2 - 8 Data, 1 Parity, 1 Stop
3 - 8 Data, 1 Stop
5 - 7 Data, 1 Parity, 1 Stop
<parity> - determines how the parity bit is generated and checked, if
present; setting this subparameter is mandatory and has a
meaning only if <format> subparameter is either 2 or 5.
0 - Odd
1 - Even
AT+ICF?
Read command returns current settings for subparameters <format> and
<parity>. If current setting of subparameter <format> is neither 2 nor 5, the
current setting of subparameter <parity> will always represented as 0.
AT+ICF=?
Test command returns the ranges of values for the parameters <format>
and <parity>
