Nut upsdev - Mar 2023 - Free and well documented NUT driver protocol

Hi Stuart,
Thank you for the link. It does seem what I am looking for. Are you aware 
of any similar standard created for a serial device? I have a working CDC 
usb setup, which is why I am asking. If required, will switch to HID though.

I don't think there's a fully documented spec for a standard serial
protocol for controlling UPS, the best you're likely to get is a common
reverse-engineered one, there's some advice in the old list post at
