Checksum. This is calculated from the start of

the message, including start identifier and

excluding CRLF. It is created by adding all

the 1s. If the sum is even, 0 is returned. If the

sum is odd, 1 is returned. This is math-

ematically the same as sequentially running

an XOR on each bit of each byte.
