Example:

Your PC is set to 19200 baud, i.e. higher than the maximum GSM transfer rate of 9600 bit/s. This means that the GSM module receives more data from the PC than it can transfer to the GSM network. In order to prevent a data overflow, the module must be able to interrupt the data flow from the PC. This is accomplished by means of the RTS/ CTS hardware data flow control.

ATBn - Select GSM module’s operating mode

The ATBn command also allows you to set the GSM module’s operating mode perma- nently for all connections.
