I have a configuration problem relating to xen's implementation on
CentOS-5.  I wish to configure a server running CentOS-5 as a Hylafax
server.  I desire to connect two external modems to the two available 9
pin serial ports on a HP/Compaq D51S P-4 host.  After some research I have
altered the grub.conf file to say this:

title CentOS (2.6.18-53.1.4.el5xen-com1)
        root (hd0,0)
        kernel /xen.gz-2.6.18-53.1.4.el5 com1=38400,8n1
        module /vmlinuz-2.6.18-53.1.4.el5xen ro
root=/dev/VolGroup00/LogVol00 rhgb quiet console=xvc xencons=xvc
        module /initrd-2.6.18-53.1.4.el5xen.img

This allows me to to configure and use ttyS1 but I still cannot enable
ttyS0.   Can anyone here give me the configuration changes needed to
employ both serial ports for fax modems?  It is highly unlikely that this
machine will ever host any virtual OS instance.
