 * PreCondition:    Stack is initialized()

 * Input:           None

 * Output:          None

 * Overview:        Checks for incomming traffic on port 30304.  
 *					Resets the PIC if a 'R' is received.
 *
 * Note:            This module is primarily for use with the 
 *					Ethernet bootloader.  By resetting, the Ethernet 
 *					bootloader can take control for a second and let
 *					a firmware upgrade take place.
