As I've just learned myself, <kbd>Ctrl</kbd>+<kbd>D</kbd> does not 'send EOF' but sends EOT. EOT after not input (or after all input is already sent) makes stdin to have EOF. But when you input "ABC" and then <kbd>Ctrl</kbd>+<kbd>D</kbd> it will just send the buffer to the process and not 'signal' EOF.

If you redirect input from /dev/null it will EOF immediately.
