"... should stop only when we send CTRL_C"

If you need to use "internal command, of our company", I'm wondering if the value of "char" should be a 'Ctrl-C' character (i.e. a single character with the ASCII code 3), instead of the 6-character string "CTRL_C". Here's a couple of ways to generate a 'Ctrl-C' character:

3
$ perl -E 'say ord "\x{3}"'
3
