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?

Hi Charles,
attached there is a patch for a new version of riello drivers:

Changes:

	-	small changes in riello_usb.c and riello_ser that solved problem with UPS
that not support realtime autonomy calculation (and also internal temperature);
	-	the second problem I think is related to the first because the shutdown
command that I sent to UPS by NUT monitor works without problems;

Cheers,
Elio Parisi.
