Configuring Serial over LAN - Can't login on ttyS0

Latest response

I am setting up SoL on Cisco UCS, I have everything working great up to the point when I try to login, as both root and non-root user.   I have verified that speed, flow control, and term emulation match between my BIOS settings and /etc/init/ttyS0.conf.   I can enter the BIOS screens and the grub menu, but I just can't login.  I'm wondering if SElinux might be blocking it.

 

I'm also having an issue with 5.5, in this case I can login fine but the startup messages are a stream of control charaxters.

 

I have followed the KB article.

Any thoughts?
