BREAK_TO_DEBUGGER is a no-op on most (if not all) sparc64 serial drivers. Everyone appears to be settled on ALT_BREAK_TO_DEBUGGER now (which makes the console line no longer clean for transferring arbitrary binary contents). I once committed a BREAK_TO_DEBUGGER patch to the sab driver. > I should also mention that I do get the serial console I'm expecting > if I unplug the keyboard on my Ultra-10, but on i386 I can get serial > console behavior while the keyboard is still plugged in.

IMHO, you can force it to use the serial console by setting the input-device and output-device variables in OBP to ttya. But then you lose the openfirmware console (terminal) emulator on the graphics device.
