Destroying a computer.

Hello! I found a bug. A way to destroy a computer so it can never be used again, that should not work.
I found it while trying to receive messages while the user interacts with a shell, but completely ruined my computer to the point of no return.
In your startup file:

function os.pullEvent(str)
 if str == "modem_message" then
  --Some code you don't need to see here
end

On startup, it will wait about 4 seconds, print a java error, say press any key to continue, and you can't press any key to continue.
Why is this a bug? Well, I found a way to disable ctrl+s and crtl+r, which are hard coded.
Feedback?

Ctrl+t is not hard coded, it's part of the function you redefined. and ctrl+s will not work when the computer shutsdown, which your redef of pullEvent has made it do. Make a startup on a disk with just return on it and place it in a drive by the comp.

Ctrl-T is coded on the Java side to throw a "terminate" event. Whether that's "hard coded" or not depends on whatever your criteria are. This isn't a bug, you're just doing it wrong. Post your code to Ask a Pro.

Locked.
