I apologise for not following up. I relocated my UPS and a Pi is acting as the NUT server now, running several devices. As a result I am unable to easily connect my main OpenBSD desktop to test. However I am setting up another machine and will have a chance to test the fix soon.
I am still running upsmon on my desktop which is working fine but this is just the net client. Thanks to everyone for the rapid fix, and in particular sthen@ for his prompt and helpful responses. Regards, Anindya
