Hi, Simon,
Yes, I''ve had serial console working for a while. Could you be more
specific when you say that no input can be sent across? Two things that
jump to mind --- first, are you spawning a TTY for the serial line in
/etc/inittab like the following:
T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100
second, do you have a ttyS0 entry in /etc/securetty?
You''ll need these two things if you actually want to login via serial
console.

Here''s my grub entry for xen/dom0 serial console:
title XEN (Serial Console)
root (hd1,0)
kernel /boot/xen.gz dom0_mem=262144 com1=115200,8n1 console=com1 \
cdb=com1 sync_console hvm_debug=0x1c0
module /boot/vmlinuz-2.6-xen ro root=/dev/hda1 nosmp \
console=ttyS0,115200,8n1
...but like I said, most likely, it''s the /etc/inittab and
/etc/securetty entries that are missing.
Hope this helps.
