It is display dependent what display does with control codes.  \007 is ANSI 
ascii control char which only works to beep on ansi terminals or emulation 
thereof.  On PCs and  Windows, displays have extended char set that prints 
most all char codes.  \007 prints as a square box.  IBM EBCDIC terminals 
would probably do third thing.
