communicating and storing data. (Alas, the added members were
scattered through the structs by our firmware designer, instead of
being added only at the end. Sigh.)

Hey, that's me! At least part of the time, so I must be part time evil....

I was a firmware guy, but I was never close to being a HW guy. Now I'm a
SW guy. However, BWAHAHAHAAA!!!!!
I agree that the best solution would have been for the new members to be
added at the end, but the FW developer might have been told that all of
the old units would be upgraded so this situation would not arise.
