+IFC DTE-Modem Local Flow Control
This extended-format compound parameter controls the operation of local flow control
between the DTE and the modem during the data state when V.42 error control is used or
when fallback to non-error control mode is specified to include buffering and flow control. It
accepts two numeric subparameters.
Syntax: +IFC=[<modem_by_DTE>[,<DTE_by_modem>]]
<modem_by_DTE> Specifies method DTE will use to control flow of received data from
<DTE_by_modem> Specifies method modem will use to control flow of transmitted data

+IFC=? Reports supported range of parameter values.
DTE-Modem Local Rate Reporting
This extended-format numeric parameter controls whether or not the +ILRR:<rate>
information text is transmitted from the modem to the DTE.
Syntax: +ILRR=<value>
<value>
+ILRR?
+ILRR=? Reports supported range of parameter values.
The <rate> reported is the current (negotiated or renegotiated) DTE-modem rate. If
enabled, intermediate result code is transmitted after any modulation, error control or data
compression reports are transmitted and before any final result code is transmitted. The
<rate> is applied after the final result code is transmitted. The DTE-modem port rate
changes only if neither buffered mode nor error controlled means are enabled (+ES=x,0)
and if the negotiated carrier rate (+MRR) does not match the current DTE-modem port
rate (auto detected from previous command line).
Syntax: +ILRR: <rate>[,<rx_rate>].

Reports current or selected values.
Disables reporting of local port rate (+ILRR: is not transmitted). Default
Enables reporting of local port rate (+ILRR: is transmitted).
Decimal value representing the current (negotiated or renegotiated)
DTE-modem rate: 0, 300, 1200, 2400, 4800, 9600, 19200, 38400,
57600, 115200, 230400
Optional decimal value reporting the RXD rate, if it is different from the
TXD rate: 0,300, 1200, 2400, 4800, 9600, 19200, 38400, 57600,
