RS-232 Word Length: Data Bits, Stop Bits, and Parity
Data Bits sets the word length at 7 or 8 bits of data per character. If an applica-
tion requires only ASCII Hex characters 0 through 7F decimal (text, digits, and
punctuation), select 7 data bits. For applications which 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.
Note: When using 7 Data, 1 Stop, Parity None, the host must insert at least a 1
bit delay between characters. If this is not done, a different RS232 Word
Length format must be used.
