You mentioned serial cuaa1, make sure there is not conflicts and here is
something that may interest you.
from /usr/src/sys/i386/boot/biosboot/README.serial:
...
- Using a port other than COM1 as the console requires some recompiling.
Again, it's usually assumed that COM1 will be available for use as a
console device on a dedicated file/compute/terminal server, so hopefully
you'll never need to do this. But if you feel you must change the
console
to a different port, here's how:
o Get the kernel source package.
o Edit /etc/make.conf and set BOOT_COMCONSOLE_PORT to the
address of the port you want to use (0x3F8, 0x2F8, 0x3E8 or
0x2E8). Only COM1 through COM4 can be used; multiport serial
cards will not work. No interrupt setting is needed.
o Create a custom kernel configuration file and add appropriate
options. For example, if you want to make COM2 the console:
options "CONUNIT=1"
options "CONADDR=0x2F8"
o Recompile both the boot blocks and the kernel.
o Install the boot blocks with the disklabel command and boot
from the new kernel.
...
This is taken from the 2.2.8-REL sources so if you're already up to
3.x then you might want to reread on how this changed.
Hope that helps,
