Serial Baud Rate
Your MultiModem Cell is defaulted to a serial baud rate of 115200 from the factory. To enjoy faster baud rates, you can
manually set the modem to a higher speed (230400, 460800, or 921600) using the AT+IPR=<baudspeed>. However, you
must make sure the host serial port is capable of the new speed. If the new speed is set and the host hardware is not capable
of the higher speed, you will need to find a host that is capable.
