+// Description
+//	   This function initialises uart interface for AVR. Available modes are 
+//	   Normal mode (0), Double speed mode (1), Synchronous master mode(2). 'baudrate' 
+//	   decides baudrate for communication. For baudrate settings, variable 
+//	   'XTAL_FREQUENCY' is required. 'stopbits' sets no of stopbits for data 
+//	   packet. 0 for 1 stopbit and 1 for 2 stopbits. 'parity' decides parity bit
+//	   for communication. 0 for disabling parity bit, 1 for even parity and 2 
+//	   for odd parity.
