I don't remember if it worked with rcons.  

consdev is a virtual device that has pointers to the read and write 
routines.  If you have a keyboard and display, you already have the read 
and write vectors pointing to different drivers.  Swapping one of them for 
the serial port read or write routine is trivial.  wscons precludes that.
