That was a typo in my first post. I am using /dev/ttyS0 - with a bit S :)
I have also noticed that there's no tty* in "dmesg | grep tty" or grep tty /var/log/demsg
could this be the problem / reason? I'm running CentOS 5.1 x64 with Xen 3.0 kernel
hmmm. 5.1 i686 w/o xen...

ok, so I think this is the problem then :)
[root@venus /]# grep tty /var/log/dmesg Xen virtual console successfully installed as ttyS0 [root@venus /]# setserial /dev/ttyS0 Cannot get serial info: Invalid argument [root@venus /]#
It may seem that Xen uses ttyS0 for itself, but how do I get around it?
