Maybe. It could also be speaking a dialect of the Megatec protocol and  
use 'QS\r' to query for the status. The new 'blazer_(ser|usb)' drivers  
will support that, the 'megatec(_usb)' doesn't.

[...]

Running a driver in debug mode might help to find communication  
problems, but if the UPS 'speaks' a different protocol, it most likely  
won't reveal anything. At best it will just echo the command back to  
let us know it doesn't understand it.

If available, running the software that was bundled with the UPS on a  
Windows box while running a serial port sniffer, usually provides  
enough info about the protocol to see what driver should support it.
