[Nut-upsdev] [PATCH] fentonups patch to make it work with some powercom ups's

[Vladislav Bogdanov]

Hi list

here is the patch to make fentonups recognize some PowerCOM's UPS's, and 
to setup terminal lines for them (at least for SMK-1500a) as powercom's 
original upsmon do. fentonups -x powercom works correctly with SMK-1500a 
(it screamed ''Communications with UPS lost - check cabling' or 'Short 
read during UPS id sequence' without this patch).

Sorry for sending as attachement, I'm not sure about right patch 
formatting in the inline post.

I'm not in list, so please send me copy if/when replying.
