Chances are le' Sun is looking for a signal to come up on the RS232 port and it's halting in monitor/prom. You can tell le' Sun to use a tty port, which one, and even what baud rate. But as far as I know ... You can't tell the machine it doesn't have a head! How would you feel without a head!??! If your problem is that you simply don't have a terminal, then make a strange cable. Otherwise, you be oudda luck...(afaik) ---- BTW: here's how you change the console/tty baud rate (did I ever post this information here??!)
