I'm gona re-reply here, to preserve the history.

test# cat /boot/loader.conf=20
console=3D"comconsole"

looking at the /etc/ttys entry you pasted above, will that enable serial =
console? That looks like a regular console on the machine itself.

I have rebooted numerous times, and I do get the kernel messages during =
boot on serial up to the point where getty starts (presumably... I see =
portion of the messages as nics are getting setup and then nothing).

I have some machines where serial works fine, but I have some machines =
where it doesn't and behaves the same way as described above. If =
necessary, I can provide access to a troublesome machine.

Thanks,
