I had issues when the 2.2 version branched out, so I started using the
powerpanel with that, and with some changes that Arjen did, everything
worked out and seemed stable, the problem I ran into though was
something corrupted that development driver on my system and it was no
longer useful for anything. That and I needed to get a production node
set up after a few power hits that I needed to get it up and stable.
This UPS is protecting a home network, so I don't know if you could call
this "production" and since it is set up to protect the servers on
failure I was comfortable testing drivers on this.

If I use the powerpanel driver, it either dies, or fails to start.
Here is a sample from the syslog dealing with that:

I fixed the "rejecting TCP connections" lines so that isn't important in
those logs (Forgot to change ACL's) but, since powerpanel was the first
driver I used before moving over to the cyberpower driver this morning,
I have decent logs of this problem.
The cable has been run in a way that uses shielded Serial, and doesn't
run across any noise generating items beyond FCC requirements (lights, etc).
