Data Bits sets the word length at 7 or 8 bits of data per character. If an application requires
only ASCII Hex characters 0 through 7F decimal (text, digits, and punctuation), select 7 data
bits. For applications that require use of the full ASCII set, select 8 data bits per character.
Default = 8.
Stop Bits sets the stop bits at 1 or 2. Default = 1.
Parity provides a means of checking character bit patterns for validity.
Default = None.
