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”.
