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 sub parameters.
Syntax
+IFC=[<modem_by_DTE>[,<DTE_by_modem>]]
Defined Values
<modem_by_DTE> Specifies the method to be used by the DTE to control the flow of
received data from the modem.
0 None.
1 XON/XOFF on transmitted data (XON/XOFF on
transmit data); do not pass XON/XOFF characters to the remote modem.
2 Circuit 133 (Ready for Receiving). (Default.)
<DTE_by_modem> Specifies the method to be used by the modem to control the flow
of transmitted data from the DTE.
0 None.
1 XON/XOFF on received data.
2 CTS/RTS. (Default.)
Reporting Current or Selected Values
Command: +IFC?
Response: +IFC: <modem_by_DTE>,<DTE_by_modem>
Example: +IFC: 2,2 for the defaults.
Reporting Supported Range of Parameter Values
Command: +IFC=?
Response: +IFC: (<modem_by_DTE> range),(<DTE_by_modem> range)
Example: +IFC: (0-2),(0-2)
+ILRR - DTE-Modem Local Rate Reporting
This extended-format numeric parameter controls whether or not the extended-format
+ILRR:<rate> information text is transmitted from the modem to the DTE.
Syntax
+ILRR=<value>
Defined Values
<value> Decimal number corresponding to the selected option.
0 Disables reporting of local port rate (+ILRR: is not
transmitted).
1 Enables reporting of local port rate (+ILRR: is
transmitted).
Reporting Current or Selected Values
Command: +ILRR?
Response: +ILRR: <current value>
Example: +ILRR: 0 For the default setting
Reporting Supported Range of Parameter Values
Command: +ILRR=?
Response: +ILRR: (<value> range)
Example: +ILRR: (0,1)
Reported Rate
The <rate> reported represents the current (negotiated or renegotiated) DTE-modem rate. If
enabled, the intermediate result code is transmitted after any modulation, error control or data
compression reports are transmitted, and before any final result code (e.g., CONNECT) is
transmitted. The <rate> is applied after the final result code is transmitted.
The DTE-modem port rate will change 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 (autodetected from the previous command line).
