Checksum field
The checksum field of Octagon’s command set is computed by adding
the ID field to the original Optomux type checksum. Note that by
providing the checksum in this way, Optomux type equipment treats
Octagon’s add-on commands as invalid messages while Octagon’s equip-
ment gains a unique set of commands.
