When you type ctrl-c in a console where an application is running, the
program does not "read a ctrl-c character", so there's nothing you can
send through the stream to cause the same effect.
What happens is that ctrl-c is interpreted by the console driver,
which then sends a signal (usually SIGINT) to all of the processes in
the process group of the foreground process.
You can do something similar with "kill -INT <pid>" or "kill -INT
<process group>". Read the man page for kill.
