Konsole ctrl-s freeze - feature or bug? [RESOLVED(ctrl-q)]

Now and again I accidentally hit ctrl-s while in vim for example. Simply because I usually use nedit for editing files so it comes natually to press ctrl-s before even thinking. However, this causes a problem since konsole then freezes and no matter what I try I cannot get it to unfreeze. Maybe this isn't an issue with konsole, but with the actual shell? Does anyone know if this is a feature (and unfreezing is possible) or whether it's a bug? I find it difficult to believe it's a bug since I remember having this issue way back in kde 1.

Does anyone have a solution?

Seems to be an issue with the shell, freezes my Eterm too. Chances are it's a hotkey, and there's another hotkey to cancel it and unfreeze. Dunno what it would be though, tried emacs ctrl-g and that didn't work.

It's easy to check yourself, just run an xterm.

CTRL-S per default in Linux is the Scroll Lock combo. Per default, CTRL-Q is the Scroll unlock function.

So, it is a feature.

as sipi said, its the default behaviuor for a Terminal. Most Terminals have an option to turn it off.

This behavior is configurable: Settings::Configure Konsole::Use Ctrl+S/Ctrl+Q flow control.

By the way, why not just Scroll Lock? I have a KVM switch but I can tell it to use CTRL x2. Is it because scroll lock is always so damn far away?

Since in the old days, Unix machines had no Scroll Lock key.

Moreover, they had almost nothing special keys, just characters and CTRL. So, every function needed a special combo with normal characters + with the few control keys.
(E.g. there were no cursor keys, page up, etc, so these functions was coded with CTRL+... keys, too.)
