I think you may have already solved this issue...but...
As I said, the final "telos" or "whatever" field in the MOTECOM
specifies both the serial hardware parameters as well as a message
header format. "They" who developed this system chose to use only
a few options here, and I believe it defaults to "avrmote" which
is the mica2 variety. The whole raison for the exercise is that
there are a set of classes that get instantiated when a message
is received in order to check a couple lengths and offsets, e.g.:
net.tinyos.message.avrmote.TOSMsg
In T1 there are only two others: micaz and telos. These classes
are also the basis for MIG generated message classes, but these
are re-instantiated at the user level.
My basic belief is that this is all due to CS grad students gone wild.
I don't know if the T2 situation is improved in any way since I've
stalled out on finding any reason to upgrade.
