             etherOutputDemo.c

DESCRIPTION -
	     This demo sends (broadcast) data on an ethernet network interface
	     and handles (receives) raw input frames (input data) from 
             the network interface using the ether input hook routine 
	     etHandle().

	     This is a simple demonstration of using low-level output ethernet
	     routines. The other half of the demonstration of using low-level
	     input ethernet routines is in etherInputDemo.c. etherInputDemo 
             task runs on one VxWorks system, and etherOutputDemo task 
             runs on other VxWorks systems within the same physical network.

RUNNING DEMO -
	     Place the etherOutputDemo.c file in your
	     <Tornado> dir. Depending on the target
	     you have, define the CPU in your compile line and use
	     the Makefile in the BSP dir. to compile.
	     
	     Note: One needs to change INTERFACE_NAME in etherDemo.h to reflect
	     which network interface is being used.

	     To run this code invoke the function etherOutputDemo().
