Whenever I press CTRL+S in putty the terminal seems to freeze. It's actually not, but it doesn't show anything. That is because CTRL+S initiates the XOFF command, which means it accepts keystrokes but doesn't show it. There are two fixes:
= Fix One - Temporary =
Press CTRL+Q to initiate the XON command. Anything you pressed will be shown.
= Fix Two - Permanent =
Add this line to your .bashrc file:
stty ixany
Now, when you hit CTRL+S the XOFF gets initiated but any character will start XON.
