[Nut-upsuser] The dreaded Tripp Lite SMART500RT1U and NUT

Hello Charles,

The patch that you provided appears to have worked.  The first patch
probably worked too ... but I left the driver running throughout the
rebuilding process (woops).

Some new commands being demonstrated ...
pi at raspberrypi ~/nut $ /usr/local/ups/bin/upscmd -u pi -p pi -l
SMART500RT1U at localhost
Instant commands supported on UPS [SMART500RT1U]:

load.off - Turn off the load immediately
load.on - Turn on the load immediately
reset.input.minmax - Reset minimum and maximum input voltage status
shutdown.return - Turn off the load and return when power is back
test.battery.start - Start a battery test

Doing a test.battery.start definitely works.  CLICK!  BUZZ! BEEP!  Done!

The others give me back an "OK" but do not seem to be doing anything.
Should load.off be shutting down supplied power?  I have a lamp
plugged into the UPS that I have moved around to different ports.  I
have one surge only, one switchable, and then four standard
battery/surge ports.  It doesn't seem to do anything on any of those
ports that I can tell.  If I run it twice, or try to go back and forth
between load.off and load.on, I start generating errors.

pi at raspberrypi ~/nut $ /usr/local/ups/bin/upscmd -u pi -p pi
SMART500RT1U at localhost load.off
Unexpected response from upsd: ERR DATA-STALE
pi at raspberrypi ~/nut $ /usr/local/ups/bin/upscmd -u pi -p pi
SMART500RT1U at localhost load.on
Unexpected response from upsd: ERR DATA-STALE

And then I can't pull down a status ... (at least for a couple of
minutes, and then it will start working again).

pi at raspberrypi ~/nut $ /usr/local/ups/bin/upsc SMART500RT1U at localhost
Error: Data stale

This is what my status dump looks like ...

Still have a couple of zeroes in there ... but this is better.  :-)
