With 120 volt input to the UPS:
ups.status: OL
With 97 volt input to the UPS and AVR displayed on the UPS' display:
ups.status: OL BOOST

I haven't explored to see if OpenBSD has the equivalent (or similar)
command. On the other hand, I did have a test system set up with
FreeBSD 11.0 (AMD64), nut-2.7.4_1 from the FreeBSD pkg. :)
dmseg excerpt for the UPS:
ugen1.2: <CPS> at usbus1
Result of the command, where "n" is incremented in a loop:
# usbconfig -u 1 -a 2 dump_string n
STRING_0x00 = 0x04, 0x03, 0x09, 0x04
STRING_0x01 = <CP1500AVRLCDa>
STRING_0x02 = <CTHGN200xxxx>
STRING_0x03 = <CPS>
STRING_0x04 = <PbAcid>
STRING_0x05 = <BF01512BA31>
STRING_0x06 = <read error>
STRING_0x07 = <read error>
STRING_0x08 = <read error>
STRING_0x09 = <read error>
STRING_0x0a = <read error>
I wasn't sure how high I should go with "n," so I stopped at 10.
Is that what you were looking for?
