The packet size is known if you access the driver with the C++ Newton
Communication Stack bindings instead of the NewtonScript ones. I sent
a sample code to Robert Ellison eons ago. It's probably lying
somewhere on my hard drive. Do you want it?
For that matter (i.e. considering that you'll interface with the
system via the TSerialChip P-Class), you'd better write all that in
C++ (since your code will not be called from the NewtonScript task,
manipulating NS objects will crash).

Are you sure that TinyTP doesn't work on the Newton? Dock uses TinyTP
as far as I recall. (geez, if you wrote a larger IrDA stack for MacOS
X with TinyTP & LMP, we'd be able to Dock on X, I have the
specifications on my hard drive ;)

Very probably. The hard part will be to register the port, but it is
much easier than designing the MP3 codec.
