I believe this will work for you as long as you use
sio0 (spelled COM1 by some people). Set:
`BOOT_COMCONSOLE_SPEED=<SPEED_YOU_WANT>'
in /etc/make.conf, where <SPEED_YOU_WANT> is something
like 38400, 57600, or 115200. Then recompile and install
the boot blocks as:
# cd /usr/src/sys/boot/i386/boot2
# make
# make install
Edit /etc/ttys for the correct speed and term-type. For
example:
ttyd0 "/usr/libexec/getty std.115200" vt220 on secure
.cr
