   /* this was originally 26 outcontrol calls, but on new dash that
      leads to screwed up dmx about once a minute. I tried doing 26*4
      outcontrol calls, but it still screwed up. I suspect the athlon64
      or my new kernel version is sending the parport really fast,
      sometimes faster than the pic sees the bits. Then I put a 1ms
      sleep after the outcontrol(2)'s and that didn't help either, so
      I'm not sure what's going on. Putting the parallel cable on miles
      seems to work.

      try a little pause after outcontrol(3) to make sure pic sees that
