+IPR - Fixed DTE Interface Rate SELINT 2<br />

38400<br />

57600<br />

115200<br />

If is set to 0, then automatic speed detection is enabled and also<br />

character format (see +ICF) is set to auto-detect. (default)<br />

If is specified and not 0, DTE-DCE speed is fixed at that<br />

speed, hence no speed auto-detection (autobauding) is enabled.<br />

Note: While in autobauding mode the 300 baud rate is not supported.<br />

<strong>AT</strong>+IPR? Read command returns the current value of +IPR parameter.<br />

<strong>AT</strong>+IPR=? Test command returns the list of supported autodetectable values<br />

and the list of fixed-only values in the format:<br />

+IPR:(list of supported autodetectable values), (list of fixed-only<br />

values)<br />
