Nut upsuser - Jun 2013 - help creating custom genericups configuration - RNG only!

Hello, I am trying to understand how to create a custom configuration for the
genericups driver.  My system simply signals RI on a serial port on low battery.
That's it, nothing else.   This serial port is also being used for
communications so the other lines are going to be changing all the time,
unrelated to the UPS state.  Is there a "null" upstype I can use, and
then add LB=RNG?  Or can I choose one of the other upstypes and clear or unset
the conditions associated with the other serial port lines?

I previously used genpowerd and configured it like this:
...
UPSTYPE=robot
UPSPORT=/dev/ttyS0

# type   cablep  kill          t              powerok              battok  
cableok
robot     ---           RI            0              /RI                        
---           ---
...

Is there an equivalent of "---" in genericups?

I couldn't tell whether this can be done after reading the section on
contact closure hardware in the developers guide.  Is there more documentation
on genericups?

I'm setting up nut 2.6.3 on Ubuntu 12.04.

If you're wondering, it's not a UPS, it's an interface to a mobile
robot.  Normally there is more comprehensive monitoring of the battery health by
software through other means, but if the software isn't running, this is a
fallback to shut down the computer.

I realize this is a pretty degenerate case but hope there is some way to make it
work with NUT.

Thanks!

Reed

I think it's pretty much any value other than a valid signal name. The man
page mentions "none" and "???" in various places.

What about something like this?

[robot]
        driver = genericups
        port = /dev/ttyS0
        upstype = 9
        CP = none
        SD = none
        OL = -RNG
        LB = RNG

(The upstype setting is arbitrary in this case, as all of the settings get
overridden.)

OK, I'll try "none" and see what happens.
