Sometimes I use putty to login my ubuntu machine, and use emacs to edit some text files.
But it always stop working when I save my edition in emacs ( Ctrl-x Ctrl-s ). I firstly thought it was a network problem, but the frequent happening with fix pattern(hang in save) made me do some investigation.
Answer founded
here. To be briefly, the Ctrl-s is the flow control key which send XOFF to terminal and let it stop output, one may use Ctrl-Q to send XON and enable the output.
Here is the way to disable this behavior.
echo "stty -ixon" >> ~/.bashrc
Now, putty se
ems ok.
