A headless FreeBSD server will often need a serial console. The FreeBSD handbook has an excellent [[http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/serialconsole-setup.html article]] on it, the summary can be summarized as such:
Add the following line to <code>/boot/loader.conf</code>:
<pre>
console="comconsole"
</pre>

And change the following line in <code>/etc/ttys</code>:
<pre>
# Serial terminals
# The 'dialup' keyword identifies dialin lines to login, fingerd etc.
ttyd0 "/usr/libexec/getty std.9600" dialup off secure
</pre>

To:
<pre>
# Serial terminals
# The 'dialup' keyword identifies dialin lines to login, fingerd etc.
ttyd0 "/usr/libexec/getty std.9600" vt100 on secure
</pre>

A few things to remember:
* The serial console allows root logins - to avoid this, remove the word <code>secure</code> from the line above.
* Worth noting if the server has a normal VGA/keyboard console: The console is ''either'' VGA or serial - when you reboot after enabling the serial console you will no longer get ''any'' output on the VGA console.
* FreeBSD defaults to a serial console port setting of '''9600/8/n/1/off''' - that is, speed 9600, 8 bits, no parity, 1 stop bit, no flowcontrol.
