[Nut-upsuser] PowerCom BNT2000AT ups on nut 2.6.0 - second try

Fri May 13 09:46:11 UTC 2011

Hi!
Normally nut was just worked and worked for me!
Not this time though!

Distro is Gentoo withe latest nut-2.6.0 emerged today.
Linux kernel version is 2.6.36
UPS is PowerCom BNT2000AT
"Driver" is powercom 
ups.conf looks like this! Okay so APC1 is not and APC!
 [APC1]       
        driver = powercom 
        type = BNT
        port = /dev/ttyS1
        numOfBytesFromUPS = 16
        methodOfFlowControl = no_flow_control
        validationSequence = {{11,0x42},{8,0},{8,0}}
        shutdownArguments = {{1,30},y}
        modelname = BNT2000APT
        serialnumber = 2233445566
        desc = Computer Room Small UPS

I running /lib/nut/powercom  -a APC1 -DDDDDDDDDD  (Okay so the debugs are 
overboard!!!)
Result is this!

Only strange think I could see is the label on the back of the ups proclaims 
it to be BNT 2000 APT. The lable lists both AP and APT but the APT version is 
the selected one!

I'm not great c programmer otherwise I would have given it a go!

So anyone any ideas? I have just had a scsi disk scribbled over in the /var 
filesystem thanks to poor power on the site and NUT not working!

Cheers
Ang
