I tried setserial and the ttyS0.conf, still couldnt get it to start. I did change grub.conf but
for some reason the system wouldn't boot properly. I'm guessing I screwed up the entry to have
both ttyS0 and /dev/console get output, so I gave up on seeing boot messages on the serial port.
I ended up creating a QND script:
# chkconfig: 1345 20 39
# description: starts ttyS0
# processname: agetty
/sbin/agetty -L -f /etc/issueserial 115200 ttyS0 vt100
Then I ran chkconfig --add start_ttyS0
Im sure this isnt the "correct" solution, but since the illustrious engineers decided to change
the way to kick off serial connections from 5 to 6, I'm just glad I have a working solution.
Thanks for the response, even if it wasn't the the method I ended up using.
