Ah, good, my bug fix is working! The driver now notices that the UPS
is buggy, and then uses the more likely value, in this case, 618.

I'll have to study this one tomorrow!

This one is wrong. Probably a miscalculation by the driver. The raw
hexadecimal value is 0x049c, which is 1180, which very likely means
118V. I will need to track down the reason the driver reports 156V;
perhaps a problem with units.

This is equally strange. Here, the reported raw value (269.00) very
likely means 26.9V, which would be correct. However, upsc reports

> battery.voltage: 0.0

What this shows is that the UPS is likely functioning properly;
hopefully with a few driver touch-ups, I will be able to coax it into
reporting the correct values. 

Gotta go to bed. More in the next few days... -- Peter
