Description of Problem: Pico crashes when pressing Control-x followed by Control-s. This is the keystroke used in emacs to save a file. Version-Release number of selected component (if applicable): RedHat 7.3 release. How Reproducible: Press C-x C-s in pico. Additional Information: This behavior occurs in other versions as well.
No, it doesn't crash.. What you're doing, is pressing CTRL-S, which is XOFF flow control. This causes the terminal to no longer send data. Press CTRL-Q to re-enable flow control. Just don't press CTRL-S when running pico or other applications, it is working as designed.
