Command Description

The test command returns the values of the supported automatically detectable bit rates and the values of the supported fixed bit rates.

The read command returns the current bit rate of the interface.

The write command specifies the bit rate to be used for the interface. When you set a fixed rate, make sure that both TE (DTE) and TA (DCE) are configured to the same rate.

The setting is stored in the non-volatile memory and will be used when the ME is powered up again. However, in case of autobaud mode (AT+IPR=0) the detected TA bit rate will not be saved and, therefore, needs to be resynchronized after restarting the ME (see Section 4.9.1, Autobauding).

Parameter Description
