Nut upsuser - May 2006 - Which driver should be used for PowerMan 2000 Real Smart ?

Hi, folks!
Which driver should be used for PowerMan 2000 Real Smart?
Backpro 1000 Plus is successfully monitored by genericups/upstype=4,
but this's not working for RealSmart2000. Somebody wrote in blogs
at http://k001.livejournal.com/270848.html that RealSmart
can be monitored using "fentonups" driver but this is false on my box.

WBR, Ilya
