	History     :    June 21, 2005 : company address updated
	                 July 12, 2005 : include file names updated
				  October  6, 2007 : TMC428 Eval PCB answer string request added
                                                                            
    Description : Example of basic TMC428 access using 'rs232win.c' via RS232  
                  interface under 32 bit MS Windows using TMC428-Eval board.   
                                                                            
                  To adapt to own SPI interfaces, the routine 'tmc428spi' has     
                  to be replaced by an other own one (see 'tmc428spi.c')
