On UNIX systems, the default terminal mode requires that a user
press the Enter key to submit a line of text. This mode allows the use
of line-editing characters, like backspace, before the input goes to the
program. The terminal is known as in "cooked" mode. So we need to use
the "raw" mode, which enables one char-at-a-time mode.

Either we use the harder way (system calls) or the easy way is to use
stty like this (this works on any Unix system) :

	system("stty raw");

	c = getchar();
	printf("%c (%d)\n", c, c);

	system("stty cooked");

Do you like this way or system calls (but I don't know about the
portability issue) ? Tell me before I do it.
