I never used the Ultra 5 but it looks close from the Ultra 10.

It depends on the setup of the Sun. A is the default, but may be the
previous owner changed to B. 

There is no automatic fallback from A to B.

If you want to use B and have no screen but a keyboard, you can type:

STOP-A (to go to the console)
setenv output-device ttyb
setenv input-device ttyb
reset

Yes
