How to STOP-A from 'tip hardwire' session

Question: I have a Sun box (Ultra 1) which I am using to 'tip hardwire' into an E4500. I watch extended diagnostics and then it starts to auto boot. I want to STOP-A so I can get to the OK prompt and then set the 'auto-boot?' variable to false, but when I hit STOP-A, it affects the local machine (Ultra1), not the E4500. Is there a key combo that I can use to send STOP-A (or something similar) to the E4500 instead of having it affect the local machine?

I know I can use HyperTerminal from a Windows box and CTRL+Break, but I would like to know how to do this from a Sun machine...

Thanks in advance!

Try this keypress: ~#
You also can end your tip session with: ~.
Or if you want al the tip commands: ~?

you need to map STOP-A to another key which sends the code of the STOP-A key in your tip session. Try using loadkeys.

filiep, your suggestions stops the local machine too.

ahoffman - filep's suggestion should work fine without stopping the local machine - I've never had a problem with this.

One more thing - check that breaks aren't disabled in /etc/default/kbd. See the file for more details.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

.. but krimsen wants to stop the remote machine. Or did I misunderstand his question?

I haven't been able to try this all day, but when I do, I will dole out the points to the first person with the right answer. Thank you everyone for your suggestions...

In answer to your question, ahoffmann, I am tip hardwired from an Ultra1 into an E4500 and I want to hit a key on the Ultra1 that will let the Ultra1 continue to run CDE, but will stop the E4500 from booting (auto-boot? was set to true) and get me to the OK prompt...

Again, thanks all!

exactly as I understood it.
As I said you need to remap any other key to the keycode sent by STOP-A in your shell on the E4500.
Probably you may also try to unmap the STOP-A on the Ultra, and then map it agin in the shell on th E4500. Not shure if this works (can't test myself).

ahoffman - this is fine - if you are tipped from the u1 to the e4500, and on the u1 press ~#, you will stop the e4500.

Perhaps this will work:
login on the E4500 as root
goto /usr/platform/sun4u/sbin (where sun4u is your platform name)
execute the eeprom utility :
./eeprom auto-boot?=false

Yes it has been a while. My apologies to all. I have been away. This solution worked for me. Thank you for your patience.
