This could mean several things.
* perhaps your UPS does not report "on battery". Does it report "low
battery"? The latter is all that is technically needed to shut down
* perhaps your UPS or cable is broken, or partially broken
* perhaps your UPS is not contact-closure. Maybe it expects proper
serial port communications, instead of setting individual pins?
In this case, you should use one of the serial drivers.
