I tried enabling and disabling it.
I kept it disable, because I have it disable for the SS20, I guess my 
cable-contraption looses it?
With a genuine cable I use for the Netra(s), I can use hardware flow 
control.

Usually at least a character, some garbage... I really get nothing.

I wonder... I think it should drop to serial without keyboard, right?
If I force in/out devices to ttya, attach a monitor, I see a black 
screen, so these OF parameters do something...

Further reasoning, even if I don't get OF, I still have old NetBSD 
booting and I don't get a login console (constty). So it appears as if 
the hardware is disbled

I hope my UART didn't break? Or is it hidden?

When booting, can I check in dmesg for a device that would represent serial?
