After a normal boot, it reads: Only in the source code. > kern.console: consolectl,/ttyd1,consolectl, Not even the bug that syscons's consolectl device is printed here is documented (the actual syscons console is on /dev/ttyv0, but this bogusly shares a tty struct with /dev/consolectl and many things cannot tell the difference. This bug also messes up the columns in pstat -t, since consolectl is too wide to fit). Anyway, the stuff to the left of the slash in the above is the list of active consoles and the stuff to the right of the slash is the list of possible consoles. You have to move stuff from one list to the other. I vaguely remember that this is done using '-' to delete things from the left hand list and something more direct to add them. Bruce
