Hi Vaclav,
I think a minor rewrite of the microchip code is probably easiest, but the
code is quite spread out, and, i also don't think it uses anything like
threading, so couldn't cope with more than one request. I only really need
to know the syntax to recreate the packed structures. Unless the structures
are packed by default in SDCC.
