Actually, if the serial line works properly, you should get other
output during boot, such as the OpenPROM version and some mem testing
info if I remember it correctly.

speed should be 9600 bps (Not 2400 which is a common default value in
some terminal software) I don't remember the settings for start/stop
bits and flow control, but you should be able to figure that out.
Not until the serial line is working correctly and you get that other
info, you can send a break signal and get your OK. Btw, in case you
