We use the `exceed tool to connect to our UNIX servers, but sometimes the command-line behaves erratically. When I am typing some command on the command-line, nothing happens -- nothing is displayed on the screen and I need to close the terminal and open a new one. Why does that happen?

Is it related to stty sane? I have typed stty sane thinking that it is used when your command-line starts behaving erratically; is that what it's for?

I'm not sure if it is what is happening in your case, but pressing Ctrl+S will freeze the tty, causing no updates to happen, though your commands are still going through. To unfreeze the tty, you need to hit Ctrl+Q.

Again, I'm not totally sure this is what is happening in your case, but I do this by accident often enough, that it is possible it may affect others as well.

unfreeze is "Ctrl + q". Are you a Dvorak user too? :-) –  Stéphane Gimenez Aug 9 '11 at 21:18
