That is what my CyberPower 1200 does.. I changed the drivers around to 
work somewhat, but as you see, they don't work well.  I've been working 
on coming up for the proper commands for the ups, but I haven't had time 
to swap out the UPS and hook it to my windows machine to do some serial 
debugging.  I plan to do this during my christmas break..
