Nut upsdev - Jul 2010 - Liebert ESP II driver

Hi Guys!

I'm back and work on this driver again.

First,

I checked out the HEAD rev and tried the liebert driver.
it gave wrong model,firmware,serial, mfr date value. caused by len variable
in line 97 and after
I use my ups with usb -> serial converter.

these patches attached

Did you try the liebert-esp2 driver in ON Battery mode ?

Because If I switch my ups on battery (plugged off the input) then liebert
driver force shutdown PC and shutdown UPS.
Battery is full charged. UPS doesnt recieve LOW BATTERY EVENT.

the shutdown function is missing from liebert-esp2 driver, this is the
reason the force shutdown ?

Thanks your advice an help.

If you provide the debug output, this will save us looking up the last  
time you posted the results.
> I use my ups with usb -> serial converter.
Which one?

I don't have one, so I can't tell.

In it's present state, the liebert-esp2 driver can't shutdown the UPS.
> Battery is full charged. UPS doesnt recieve LOW BATTERY EVENT.
How old are the batteries? When was the last time you ran a battery  
test? This sounds more like a bad battery than a driver problem. Worn  
out batteries are a common cause of mishaps like these, where the  
batteries seem to be fine when not loaded (mains present), but fail  
under load (mains failure) within seconds.

The driver won't be able to shutdown the UPS if the upsdrv_shutdown  
function is not functional. If the UPS kills the output, it is not  
caused by NUT but most likely by the battery protection.
