and odd checking, the serial port will set up a parity bit right, with a value of the data to keep
transmission digits in even or odd number. For example, if data is 011, then the parity bit is
0 to guarantee logic high median is even number. When in odd check, then the parity bit is 1
so that there are three logical high digits. The high and low bit do not actually check the data
information, but only through a simple logic check. This makes receiving devices to know if
there is a noise interferes in communication or whether transmission and reception of data is
not synchronized by digit status.
