All you need to do is to enable a getty on a serial port, e.g.
by editing /etc/ttys:

console none                            unknown off secure
ttyd0   "/usr/libexec/getty std.9600"   dialup  on secure

If you don't plan to attach a monitor (or don't have a VGA circuitery
at all on the box), you can also turn 'off' the virtual terminals
ttyv? in /etc/ttys

You can also add this to /etc/syslog.conf:

# uncomment this to log all writes to /dev/console to /var/log/console.log
console.info            /var/log/console.log

And double check the entry for /var/log/console.log in /etc/newsyslog.conf:

/var/log/console.log                    600  5     100  *     J

After rebooting, you can connect to the serial port with 9600 8N1.
You may want to use a crossed serial cable (null-modem cable) for this.
