Re: STDIO DISPLAY ON BL4S200

If nothing's connected, it shouldn't matter that you're still sending output to STDIO.

If you're using the Rabbit's built-in methods to redirect STDIO to a serial port, then I don't think there will be an easy way to conditionally send output.  You'd probably have to create a wrapper for printf() that checks an I/O pin (CTS on the serial port?) before handing the parameters off to vprintf() using a va_list parameter.
