3.5 SPECIAL CONFIGURATION COMMANDS
3.5.1 AT%Bn
Fixed DTE Baudrate.
This command 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. Must be the
last command in an AT command line. If automatic baudrate detection is enabled,
after power-on any messages (i.e. RING) will be send with 115’200bps in the case
that no AT command was entered before.
