I thought that Suns only beep when powered on with a keyboard connected  
(the speaker that beeps is inside the keyboard; the box itself doesn't  
have a buzzer, aside from the soundcard).  Then again, the newest thing  
that I have is an Ultra 60, but I remember when I got it, the seller said  
that he didn't know if it was working.  It turned out that it was  
configured to only accept input and display output through ttya:

| {0} ok printenv
| Variable Name         Value                          Default Value
| output-device         ttya                           screen
| input-device          ttya                           keyboard

I'd definitely try it with the null modem cable; it might turn out that  
it's not even trying to use the screen and keyboard.
