Sort of. In the sense that if you select a serial console, the green
output goes to the serial port and not to the VGA screen. Johnny is
correct in pointing out that perhaps I should not have called these
switchable virtual terminals "console", but people are sloppy and the
thing is called "wscons" which makes it harder.

You can even change the console in an existing installation (although
personally I've never needed it). Look at the manual page of
installboot, and the option -o console=... .
You can also (for the current boot only) set the console from the boot
loader. See manual page boot(8), command "consdev".

If you have a serial terminal at hand, it is always fun to try. I
operated a DEC Alpha with a serial console, even though it had display
hardware.
