[Nut-upsuser] [Nut-upsdev] CyberPower 550SL reports LB and OB when on line power

[Charles Lepple]

[please keep the list CC'd. There are other people there who know way  
more about this driver than I do. It's also more of a question for  
nut-upsuser since genericups can be reconfigured at runtime.]

I would try setting the OL and LB parameters in ups.conf to match  
what you are observing. See 'man 8 genericups' for more details (from  
the NUT source directory, 'man man/genericups.8'

For instance, if CTS goes low when the battery is low, it would be  
'LB=-CTS'

The 'statserial' program is also helpful for monitoring the serial  
port signals in real-time.
