Run this (as all one line:)
chdev -l tty0 -a
runmodes=hupcl,cread,brkint,icrnl,opost,tab3,onlcr,isig,icanon,echo,echoe,echok,echoctl,echoke,imaxbel,iexten,clocal
-a logmodes=hupcl,cread,echoe,cs8,clocal
I think that missing "clocal" on logmodes will make the system not even
put up a login prompt if it's missing the right handshaking lines,
which sounds like it's what your problem may be.
