On most Sun systems, the console is a bit-mapped display used for windows,
not a serial line type device.  The various window systems (X, NeWS,
SunView, etc.) allow you a terminal window which acts as your console.
This way, rather than having console messages mess up your windowed
display, they go into a window.  I imagine this is what the pseudo-console
is referring to.
