My Smart UPS 1400 is now being monitored/controlled from dom0 with apcupsd.

But, I don't know if that will fix the above warning.
It's absolutely ages since I used serial ports under Linux -- I mean 10 years at least -- but my recollection is that they are called things like ttyS1 (with the 'S' in there).
I have another question: can I hand the serial port to a domU, or does it have to be present in dom0?
There's a bit about this on the Xen wiki: http://wiki.xensource.com/xenwiki/InstallationNotes#head-327388b324997719e864f8740fed06036c799e38 Rich. -- Emerging Technologies, Red Hat - http://et.redhat.com/~rjones/ Registered Address: Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SL4 1TE, United Kingdom.
