Hi,
I was trying to install FreeBSD on SB150 and since it didn't support the
Graphics card, I wanted connect through serial console. I by mistake set
both the input-device and output-device to ttya and I also I have enabled
diagnostics. Now I'm not able to get to the OBP.
I connected through a null-modem cable and i tried using Linux/minicon,
Windows/Hyperterminal, and Windows/TeraTerm. I tried send to break,
cntl-break, shift-break with no luck. I can see all the diagnostics messages
and it always stop with these messages

---------------------------
Nothing after this.....
I tried STOP-N to set it defaults so that I can use the Sun keyboard again.
It didn't help.
I tried [return] ~ [ctrl-b] and it didn't help either.
I'm not sure the state of the default boot variable.
I'm not sure what else to try.
Please help recover the system back to OBP.
thanks for any suggestions
Suresh
