Prevent the line discipline from handling control characters When you send a control character from the terminal, for example if you pressed `Ctrl+C`, the _line discipline_ will receive the byte representing this control character (which is `0x03` in the case of `Ctrl+C`). Now instead of the _line discipline_ sending the byte `0x03` to the program associated with the terminal, it will instead send it the `SIGINT` signal (or it will do some other action if it is a different control character). Now is there a way to prevent the _line discipline_ from handling control characters, so what I want is for the program associated with the terminal to receive the actual bytes representing the control characters (`0x03` in our case).

On linux, you'd use


$ stty intr undef


on the terminal concerned. That sets the interrupt character to nothing ("undef"). To restore you would use


$ stty intr ^c


See `man stty` for details.
