Configuration
Parity Bit: Parity is a form of error checking used in serial communication. For even and odd parities, the serial port sets the parity bit
(the last bit after the data bits) to a value to ensure that the transmission has an even or odd number of logic high bits. For example,
if the data is 011, for even parity, the parity bit is 0 to keep the number of logic-high bits even. If the parity is odd, the parity bit is 1,
resulting in 3 logic-high bits. Parity can be set to No (none), Even, and Odd.
