Re: Control Scheme

I agree with Tom here.  Keep the Stamp doing very
primitive things and don't give it the ability to
interrupt the host PC.
  In regards to using a pure binary format for
commands to the Stamp:  I don't think it is necessary.
There is no command that has to be acted on quickly
or for which a fast reply is needed, except for the
shutter operations.  Note that a shutter open command
in pure ascii might be something like "OP<cr>", about
three ASCII characters plus perhaps an ACK back to
the host PC.  At 9600 baud, this is only a few milliseconds,
plenty fast enough.  Keep everything ASCII -- it is
*much* easier to debug!
