 	On my desk are a BackUPS 650, a BackUPS Pro 650 (the 
oldest), and a BackUPS RS 1500 (the newest; shop said it was what 
they used -- and showed me); the newest has what looks like an 
ethernet port, labelled "Data Port"; the other two have serial 
ports. Presumably a computer, if connected, could send to them as 
well as receive, and maybe send commands; but if there's anything 
like a physical switch on the back of any of them, it's well 
disguised.

 	The oldest is from '99 iirc; the newest from two or three 
years ago; the other and the one downstairs (where I'm not asking 
my knee to go -- MRI scheduled tomorrow) were in between, all 
four bought new in stores.
