45**  CHECK IF A DEVICE IS OUT
46**
47**	The indicated device is checked to see if it is disabled.  If
48**	it is, an attempt is made to use the starbase device.  If both
49**	of these fails, it returns non-zero (device is REALLY out),
50**	otherwise it returns zero (I can get to it somehow).
51**
52**	It prints appropriate messages too.
