the active energy field is pretty sussy but it's just a 4-byte integer sucked off as 2 2-byte ones, $ printf '%4s\n' $(printf '%s\n' obase=16 58932 60 | bc) | tr ' ' 0 | tac | paste -sd\\0 | bc
399634 and that's what the LCD shows too
sysv message queues? kinda slick with it; world's most insane interface, natch, but
also thanks to @ThePhD's n3030 i can have enum or_we_504_msgtype : long { in c and c++ with -std=c2x, which makes this much less insane
