Default Checksum curiosa

The spec states that...
Quote:
The Checksum field is the unsigned, modulo 0x10000, 16-bit additive checksum of the entire packet’s slot data, including START Code.
However, the checksum covers a maximum of 255 bytes, each with a maximum value of 255, so the maximum possible checksum is 65025, or 0xfe01. So the checksum is in fact not modulo at all.

Cheers,
Shaun
