Lets use ipmi module and ipmitool instead... more options.
# ipmitool -d /dev/ipmi0 shell
# ipmitool -I open lan 
# ipmitool -d /dev/ipmi0 lan set 1 access on

Start IPMI shell;

# ipmitool -I lanplus -H 192.168.1.21 -U ADMIN shell

Use ipmitool to for serial over lan to host;

# ipmitool -I lanplus -H 192.168.1.21 -U ADMIN sol activate

Reset remote host

# ipmitool -I lanplus -H 192.168.1.21 -U ADMIN chassis power reset

Configure GRUB to work with Serial Device;

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/sda

# Redirect grub output to serial console, which is on COM Port 2
serial --unit=1 --speed=19200 --word=8 --parity=no --stop=1   
terminal --timeout=10 serial console

default=0
