You don't have to disable MOTECOM, you need one setting for SF
to get
to the serial poet, and then there is a setting...probably in
the
tutorial...that allows programs that use BuildSource to attach to
the
enet port of SF.
For the Sample error, where is it in the code? There
should be some
indication of what went wrong if you trace through. You are
getting
packets if you use Listen or ListenRaw, right?
