17.4   Machine Lock-ups and Such

No Response

I can't get any response from my machine. Can you fix it?

It's probably a flow control thing where somebody hit CTRL-S and stopped tty output. If so, hitting CTRL-Q should fix it.

For *nix -- If CTRL-Q doesn't fix it then type CTRL-Z to stop the current process. If that gets you a response then the process may be hung or just real busy.
