Relatively ancient documentation seems to suggest that this 'firmware checksum' value can be used to indicate the firmware generation as well as the capabilities of the UPS, namely the number of independently controllable plugs.
Here is where I got the information, following a hint in the driver's documentation header: https://web.archive.org/web/20161113104958/http://www.kursknet.ru/~boa/ups/stinfo_command.html
I tested the plug control on my SMART2200NET, which has two independently controllable plugs in addition to the all-inclusive load control.
