Configure a Modem adaptation baud rate

On the asynchronous interface connected to the modem, use a standard AT command to configure the modem baud rate, and send the “AT” command to the modem. If “OK” is received from the modem, it indicates that the modem can automatically adapt to the corresponding baud rate. Then, write the configuration into the modem for conservation, and the corresponding AT command is “AT&W”.
