@rzr: Sorry, first and foremost I totally forgot to say thank you very much. I really appreciate you work and effort for this "non-core" issue.
That said, I can say that it works on my test machines. I could successfully install and connected to a APC Smart-UPS 750 (SMT750RMI2UC) to my test server. Not a single problem whatsoever. I will now monitor it a bit and if I observe anything I will let you know.
Is there maybe anything particular you are interested in for me to test?
