I just had a neat learning experience with screen. My session became locked to me accidentally hitting Ctrl s instead of Ctrl a. Thanks to this post, I now understand what happened and a few ways to fix and/or prevent. The original is pretty concise so feel free to stop reading this and browse there; or just read on.
- Ctrl s sends an XOFF which stops character flow.
- Ctrl q sends an XON which starts character flow.
That is the short term fix, Ctrl q will right the ship. For longer-term prevention, add this line to your ~/.bashrc:
- stty ixoff -ixon
In short, thanks to Morgy for a great post.
