wget --user=admin --password=i3 http://i3detroit.dyndns.org:5000/cgi-bin/getdi.cgi
find "DI=H" <getdi.cgi
echo %errorlevel%
if %errorlevel% EQU 0 wget --user=admin --password=i3 http://i3detroit.dyndns.org:5000/cgi-bin/setdo.cgi?do=l --output-document=NUL
find "DI=L" <getdi.cgi
echo %errorlevel%
if %errorlevel% EQU 0 wget --user=admin --password=i3 http://i3detroit.dyndns.org:5000/cgi-bin/setdo.cgi?do=h --output-document=NUL
