If a value is not supported, the driver should not publish it with the dstate API. Dhould the driver be modified to not return battery.charge if the UPS returns 0xFF? Are there other variables that are affected?

(I don't think the IDG400 is covered in the protocol documentation that the NUT project received a while back.)

Right, NUT tells the computer to shut down, but it also typically sends a shutdown signal to the UPS. Does the IDG400 also respond to the same shutdown command as others?
