DTE Commands

Command: +IFC DTE-Modem Local Flow Control

Description: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>]]

Values:<modem_by_DTE> Specifies method DTE will use to control flow of received data from the modem.

0None.

1XON/XOFF on transmitted data; do not pass XON/XOFF characters to remote modem.

2Circuit 133 (RR). Default

3DC1/DC3 on circuit 103 (TD) with DC1/DC3 characters

being passed through to the remote DCE in addition to being acted upon for local flow control.

<DTE_by_modem> Specifies method modem will use to control flow of transmitted data from the DTE.

0None.

1XON/XOFF on received data.

2CTS/RTS. Default

Report Commands: +IFC? Reports current or selected values.

+IFC=? Reports supported range of parameter values.

Command: +ILRR

DTE-Modem Local Rate Reporting

Description:

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>

Values:

<value> Decimal number corresponding to the selected option.

 

 

0 Disables reporting of local port rate (+ILRR: is not transmitted). Default

 

 

1 Enables reporting of local port rate (+ILRR: is transmitted).

Report Commands:

+ILRR?

Reports current or selected values.

 

+ILRR=? Reports supported range of parameter values.

Reported Rate:

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>].

 

Reported Rate Values:

 

<rate>

Decimal value representing the current (negotiated or renegotiated)

 

 

DTE-modem rate: 0, 300, 1200, 2400, 4800, 9600, 19200, 38400,

57600, 115200, 230400

<rx_rate> Optional decimal value reporting the RXD rate, if it is different from the TXD rate: 0,300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, or 230400
