- Complete problem description:
Hello there!

This is my first time using a mailing list, so please let me know if I
missed something.

I'm trying to use this UPS over a serial connection with a Lenovo computer
running Proxmox. I've already been successful in using it over the USB
connection with a Raspberry Pi and both Raspbian and OpenWRT, but given
this computer has a built-in (and as of yet non-functional) serial port, I
wanted to try it out and see if I'm able to free up a USB port after all.

I am able to connect successfully using the text protocol, however, it
seems the driver times out after negotiating a link over the serial
connection. At the moment I am testing it over a USB to Serial adapter, but
even through this method the official Powerpanel is unable to detect the
UPS at all, so only NUT seems to be the option here.

If I'm able to get the UPS working over the USB adapter, I'll be able to
discard the powerpanel driver as a potential issue and move on to
diagnosing the onboard RS-232, but for the moment I hope I've included
enough information as a starting point.

Thanks for the help!
