      Z-World, 2002

      Demonstration of redirection of STDIO output from
      Dynamic C's STDIO window to a serial port (this
      feature was added in Dynamic C 7.25).

      NOTE: these macros are designed for debugging use only!
		They allow STDIO functions to be redirected to the
		serial ports for viewing in run mode -- these macros
		are not designed to be a standard part of a Dynamic C
		program (character input is not buffered, for example).

		When in debug mode, STDIO will go to the STDIO window
		as usual.  When in run mode, STDIO will go to the
		designated serial port.  This is especially useful since
		the programming port (serial port A) can be used with
		the PROG header for debug mode and the DIAG header
		in run mode without recompiling the program, keeping the
		other serial ports free for application use.

		The desired serial port is selected by adding ONE of the
		following lines to your program:

				#define	STDIO_DEBUG_SERIAL	SADR
				#define	STDIO_DEBUG_SERIAL	SBDR
				#define	STDIO_DEBUG_SERIAL	SCDR
				#define	STDIO_DEBUG_SERIAL	SDDR

		Then specify the desired baud rate with a define like
		the following:

				#define	STDIO_DEBUG_BAUD	57600

		Many PC-based terminal programs expect a carriage return
		as well as a newline character at the end of each line.
		A carriage return ('\r') can be added to each linefeed ('\n')
		in a printed string by adding the following line:

				#define	STDIO_DEBUG_ADDCR

		If serial debugging is desired even when in programming mode,
		it can be forced by adding the following line:

				#define	STDIO_DEBUG_FORCEDSERIAL
