checksum
The checksum is an XOR (exclusive OR, anticoincidence) combination of all bytes from the starting byte (delimiter)
up to and including the last data byte.
An XOR combination is the logical combination function of two logical values ("0" and "1"). It yields a result of "1"
if one but not both of the two values is "1".
