I wait for the mail on dev..

Both yes and no. This depends on the ups in use. The 3105 5110 is
not supporting this values. But if you hock it up to a 5115 you should
The code is the same for the serial and the usb driver. The things that
differs is the communication part. If you check the code you find the
bcmxcp.c file that handle the parsing of values and commands.
The bcmxcp_usb.c is the comm part for usb and bcmxcp_ser.c is for serial
So it should be the same if you hock it up on a serial line.
What we do is to check (parse) the block that list what the ups can
offer in form of values. If the value is presented it is shown.

To do this you need to know the battery charge, and the 5110 is not
showing this. So it would be hard to do a calculation on the runtime.
