[Xen-users] Re: Serial port pass-through or redirect

[Eric Camachat <eric.camachat@xxxxxxxxx>]

After some trials.
I can see console outputs (kernel printk stuff), but still cannot
access it by application.
for example:
/sbin/getty -L -n -l /bin/sh 19200 /dev/ttyS1 vt100
Will be terminated automatically.
