"...If "keyboard" is the selected input-device and "screen" the
output-device (both via /options) but the keyboard is unplugged,
OF automatically switches to ttya for the console, it even prints
a line telling so on "screen". Solaris respects this behaviour and
uses ttya as the console in this case and people probably expect
FreeBSD to do the same (it's also very handy to temporarily switch
consoles)..."
"...I changed the comparison of the console device with "ttya" ||
"ttyb" to "tty" because on AXe boards all 4 onboard UARTs end in
SUB-D connectors (ttya and ttyb being 16550 and ttyc and ttyd a
SAB82532) and there's no Sun keyboard connector (but PS/2). If one
plugs a serial card in a box there also can be more than just ttya
and ttyb available for a console..."
