[Nut-upsdev] Issue with On Line Status (APC MGE Galaxy 5500 + AP9635CH)

[mateuszx]

So what would it take me to edit NUT's code for my case to work? My Network
Management Card sends its output state using unfortunately only (I guess
so) this OID: 1.3.6.1.4.1.318.1.1.1.11.1.1.0
Weirdly the standard way of obtaining Battery Status
(drivers/apc-mib.c) 1.3.6.1.4.1.318.1.1.1.2.1.1.0
gives me good results.
Unfortunately power status OID's value type differs (my: 64 digits binary
number vs standard: integer).
I know i can retrieve each bit's value with no problem but the question is:
How do I integrate my bit recognition with NUT's nut2mib struct and so on...
I am working on drivers/apc-mib.c UPS driver
Maybe is there something relatable already in the code so I can "make my
work easier"?
