Welcome to my pain.

If you search the archives, you should find info about ttyS0 and trying
to get a UPS to use it in dom0.  Short story: still not working.

I've had the very same problem since day 1.  xencons=off indeed works,
but ttyS0 isn't created at boot.  I even tried building my own kernel,
but that didn't work either.  Though, I must admit, I have not built my
own kernels very much, so I may have made a mistake.

If you solve it, PLEASE let me know here.  My recently purchased
Smart-UPS is now dumb. :(
