I had this problem two years ago.  Turned out the serial parameters were 
set to something non-standard.  To fix it, I had to connect a sun 
keyboard, turn on the box, and press Stop-A.  If memory serves, I then 
typed:
	set-defaults
	reset-all
and it worked.

You can also try:
	setenv ttya-mode 9600,8,n,1,-
	reset-all

Of course, you are doing all this blind unless you have a monitor.
