it works...partially

spi listenening works, sorta, pokey is too slow, but we are getting
there, the pipe to xplane remains. A very dark tunnel, have I mentioned
how much I hate the win api. The many dll's, somehow the -static flag
doesn't seem to help. It'll just have to be fixed later.
at 5 baud
cut lots an a new way

changed to rs232 communication via a (virtual) com port. it works,
except registering the callback in xplane
