I often use the serial console on my servers through ILOM remote console
access to install FreeBSD because it lets me cut and paste commands into a

console worked as a dual console between the redirected VGA/keyboard console
and serial, all I had to do was drop to the loader prompt at the boot loader
menu to enter:
set console=comconsole
set boot_serial=yes
boot
From then on, the VGA console was ignored until I rebooted. But in 9.x
(currently trying 9.0-RC2 from the usb image), I have to interrupt an
earlier loader to use -h or -D to enable serial(dual) console support at
all. I then enter the two variables above as I usually do, then specify my
terminal type (xterm), then choose "Live CD" which prints:
Updating motd: /etc/motd is not writable, update failed.
Configuring syscons: blanktime.
Starting cron.
Starting background file system checks in 60 seconds.

but then it prints the FreeBSD banner and spawns the login: prompt on the
VGA console instead.
Is there something else I can set during the boot process to make this work?
I could try modifying the configuration on the usb image to suit my site
but this is more modification than I required in the past and surprisingly
different. Please let me know if I can provide more information or help in
some way. Thanks.
If I don't hear back in a few days or so, I'll make a PR.
You'll need to change your device.hints and /etc/ttys.

Thanks. This lead me to an even easier solution with no editing that
should work with booting from CD and with previous versions:
1. Boot completely normally
2. Use the installer to drop to Live CD shell
3. execute: /usr/libexec/getty std.9600 ttyu0
This spawns a login prompt on the serial port ttyu0 which is essentially
all I need. I didn't seem to need to alter the device hints at all for
my situation, and on a USB key I can mount -u -o rw / to edit one or
more of /etc/ttys, /boot/loader.conf, /boot.config if I want to make it
permanent for next time.
