10.4.20 +ILRR:m,n - DTE-Modem Local Reported Rate
The reported rate m, 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 m, 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).
Command: +ILRR: m[,n]
Defined Values
m Decimal value representing the current (negotiated or renegotiated) DTE-modem rate:
0, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, or 230400
n 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
Example: +ILRR: 19200
10.4.21 + IPR=n - Fixed DTE Rate
This numeric extended-format parameter specifies the data rate at which the modem will accept
commands during online operation. It may be used to select operation at rates at which the modem is
not capable of automatically detecting the data rate being used by the DTE. Specifying a value of 0
disables the function and allows operation only at rates automatically detectable by the modem. The
specified rate takes effect following the issuance of any result code(s) associated with the current
command line.
The <rate> specified does not apply in OnLine Data State if Normal Mode (Direct Mode) of
operation is selected.
Command: +IPR=n
Where n specifies the DTE-modem interface operation rate in bits/s. The available rates are:
0, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200
If unspecified or set to 0, automatic detection is selected and the character format is also forced to
autodetect, +ICF=0.
If the rate specified is not supported by the modem, an ERROR result code will be returned.
Reporting Current or Selected Values
Command: +IPR?
Response: +IPR: n
Example 1: +IPR: 0 for automatic rate detection.
Example 2: +IPR: 115200 for 115200 bps.
Reporting Supported Range of Parameter Values
Command: +IPR=?
Response: +IPR (n range)
