Yes...but there's an easier way.
Leave input-device set to keyboard and output-device set to screen, and
simply unplug the keyboard. When it can't find the keyboard, it
switches over to ttya for input and output on its own.
Yes this is definitely true, however it isn't always reliable. I've
run into many situations in which SPARCstation-2 and -5 systems think
there's a keyboard attached when there in fact is not, and thus become
inaccessible on the console.
This is much more important in some situations than in others,
though...I've used far more SS2/SS5 systems on shelves in racks in a
datacenter than I have on desktops. In that environment, it pays to
"lock" things where you want them rather than depend on autodetection.
I follow the same philosophy when it comes to autonegotiation of
Ethernet parameters such as speed and duplex.

I believe that Suns can be set to ignore the graphics
console [...]
At the "ok" prompt, to use ttya as the console, type
this:
setenv input-device ttya
setenv output-device ttya
To change back to the keyboard & framebuffer, type this:
setenv input-device keyboard
setenv output-device screen
