Checksum of ASCII messages is calculated as a 8-bit XOR of all characters in the message beginning from the delimiter ($) and ending at the last field separator (,) before the checksum itself.

Example of the message 25 and characters included in the checksum calculation:

$03.22,75.29,03.38,03.07,22.13,0,
