Typing "stty -ixon -ixoff" at the shell prompt will disable this type of flow control if you don't want to use it. The original purpose of this was to regulate the flow of data over serial lines, so a computer wouldn't send data to a terminal faster than the terminal could display it. These days it's rarely necessary to use it: most connections to Unix are over TCP/IP or serial lines with hardware flow control, and the only remaining use of ^S/^Q is as a way of manually pausing output. If you never need it, feel free to turn it off. -- Matthew Winn
