(...) Its a bug, fixed in the cvs version of brickOS, I believe. For now, adding: CFLAGS+=-D_WIN32 to the top of Makefile.common might work. I can't test it, because I don't have the h8300 compiler set up at the moment. -- Max. (22 years ago, 24-Nov-02, to lugnet.robotics.rcx.legos)

That looks ok to me. But I'm no expert on LNP. Here's a clip I use. It looks a lot like what you're using. It seems there may be a problem with your receive code. I'm REAL shaky on that.
