FILE LIST -
         nonBlockReadDemo.c
 
 DESCRIPTION -
 	This code is an example  of doing a nonBlocking read on a port
 	in raw mode.
 	The first read blocks and waits for a character.  It then
 	checks to see if additional characters have been sent as
 	a result of pressing a special key such as <- (left arrow)
 	If so, a special case is invoked to handle this (printf in this
 	case)
 	What to do with the data is left up to the customer.
 
 RUNNING DEMO -
 	Place the nonBlockReadDemo.c in your <Tornado> dir.
         Add this file to your project, re-build projectName.out and download it.        
 	To run this code invoke the function nonBlockReadRawStart().
