I have NUT running.  Now I need to do the final test, which is to remove power
to the UPS and see if it shuts down properly.

The documentation I have says to "chmod 0660 /dev/ttyUSB0", this appears to be
what the system sets as default.  Also to "chown root:nut /dev/ttyUSB0", the
system default is root:dialout.  This works but does not surive a boot so I
added nut to the dialout group.
