This won't give you a serial console; it will only start a getty on
the serial line during system bootup.

On some systems running NetBSD/i386 I used

$ installboot -v -o timeout=3,console=com0,speed=38400 /dev/rwd0a /usr/mdec/bootxx_ffsv1
$ echo 'console "/usr/libexec/getty std.38400" vt100 on secure' >/etc/ttys

to get a serial console and to enable logins on the serial line.

Send a SIGHUP to init:

$ kill -HUP 1
