Baud Rate
The rate at which the data is communicated with PC.
There are 4 options of baud rate: 115200 (default), 57600, 38400, and 19200.
The higher is the baud rate, the faster is the communication speed, but also the
less reliable.
Hence, a higher baud rate can be used when the communication distance is
short; when the communication distance is long, choosing a lower baud rate
would be more reliable.
