I think I'm not following you - with debug 3 -->> it WORKS -- without debug it fails. (even debug 2 fails).

Could be you want me to build a version off of github?

I see there isn't anything is sid or experimental ..

I'm rusty at building packages (keeps changing) - do you have a build script?

git clone https://github.com/networkupstools/nut

-- no debian directory ?

Not enough time to fail from not finding UPCL


This seems like this might be a timing issue - something is running before something else is ready?  Debug would slow 
something down?


I hooked it up to cutecom connected and I seem to get a list of supported commands back if I ask for UPCL


UPSS
UPDS
UPDV
UPTP
UPSN
UPPN
UPSD
UPCD
UPPC
UPPU
UPIS
UP??
UPEA
UPDA
UPCL

Looks like a list of supported commands? UPCL(Ups Command List?)



Takes a couple of seconds.


Looking at the debug output of  /usr/lib/nut/upscode2 -a malaysia -DDDD

I see a problem at :

  0.954763     [D3] upscsend: 'UPCD'
          0.956318     [D3] upscsend: '0000'

          4.960566     [D2] Got value:

          4.960609     dstate_setaux: base variable (ups.delay.reboot) does not exist

 From cutecom - UPCD 0000 returns

ACCD
