its possible the previous user changed the settings. To reset the OBP
parameters to defaults, plug in a Sun keyboard and hit Stop-A at the
Initializing Memory spinny, then type 'set-defaults' and hit ENTER at the
OBP 0> prompt.  Type 'printenv' and hit ENTER and verify the coma
parameters are set back to 9600,8n1, then power off the system, remove the
keyboard, plug in your serial console (make sure its a null modem with a
Male-Male adapter; don't plug it into the parallel port)  then power the
system on. If all the cables are working you should get the normal boot

There's another way to reset OBP to defaults by holding Stop-D, but I'm
not sure if that will carry over if you then power off and pull the
keyboard out.
