The linux stty command learns how to use the stty command to modify and display terminal line settings.

It turns out that when shell is running, it has taken over the processing of these buttons. Sh-# ps pid tty time cmd 409? 00:00:00 init 943? 00:00:00 sh 1213? 00:00:00 sh 4918? 00:00:00 pssh-# kill-2 943 sh-# Here we tested to send SIGINT signal to the current shell. As there is no command or program running in the current shell, it seems that nothing is done. You can also press CTRL + C in shell to see if it is correct. CTRL + C actually sends SIGINT to the current shell, which is equivalent. Problem to be solved: When my terminal type is/dev/console, pressing CTRL + S/CTRL + Q in shell does not work; sh-# tty/dev/console. However, if my terminal type is/dev/pts/6, pressing CTRL + S/CTRL + Q in shell will work; sh-# tty/dev/pts/6
