[Nut-upsdev] Liebert PowerSure PSA 500

[Joe Krahn]

Jochen,
Having been in contact with Liebert and a Liebert UPS developer, can you 
get a copy of the ESP-II protocol used for Liebert RS-232 communications?

I have a Liebert UPS, and am able to monitor with their MultiLink 
software, which is not that great. I actually have not tried the NUT USB 
interface yet, but it seems that RS-232 might be a better choice than 
USB, if you have the right cable and a serial port.

Thanks,
Joe Krahn
