**  CHECK IF A DEVICE IS OUT
**
**      The indicated device is checked to see if it is disabled.  If
**      it is, an attempt is made to use the starbase device.  If both
**      of these fails, it returns non-zero (device is REALLY out),
**      otherwise it returns zero (I can get to it somehow).
**
**      It prints appropriate messages too.
