</div></div>This is a historical feature of terminals, known as soft flow control.<br>
One would often use it on a very slow serial terminal connection to<br>
perform manual pagination of sorts.<br>

Some software that runs in the terminal (such as Emacs) overrides that<br>
behavior, since Emacs uses both C-s and C-q key combinations. I am<br>
relatively certain that means that there is a way to disable it<br>
generally, but it's never been a problem for me so I don't know what<br>
the process for that would be.<br>
<br>
</blockquote><div><br>Thanks for the suggestion. I use ctrl-d quite a bit and occasionally it becomes<br>ctrl-s due to typo. Great presentation on DR by the way. I just read over it.
