How to form the block check character (BCC1, BCC2):
The BCCs are formed by simply building the exclusive OR operation
byte-by-byte over all characters transmitted (incl. <STX>, <ETX>) (based
on 00hex). The bit that results is sent as hexadecimal number with two
ASCII characters.
Example:
BCC binary: 01011010
Is transmitted by the ASCII characters: 5A
