3.2.2.14 +IPR - 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.
Syntax
+IPR=<rate>
Defined Values
<rate> Specifies the DTE-modem interface operation rate in bits/s. The available rates are:
0, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, or 230400
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
