Notes on the fob code:

  0. the code relies on the two fob and serial libs that are provided -
     it should compile ok on view.vr.clemson.edu (running RH 8.0); note
     that the serial lib depends on the fob lib.

  1. the FOB on view.vr.clemson.edu is old which means:
     (a) it runs at a slower RS232 rate (38400 vs. 115200 what we use on
         our other birds), and
     (b) does not provide the leading bit that we usually use to check
         for synchronization (newer chipsets use it).

  2. the hemisphere in fob.h/fob.c code may be incorrect - the code
     is there (used to work on mickey) but this code was modified to
     work on the WindowVR device, so it's in a bit of state of flux;
     you'll have to figure out which hemispheres and angles to use to
     get it working.
