***************** PC terminal program ***************

This program is included in a Virtual Wire Development

Kit. It demonstrates the interaction of a PC application 

with the Virtual Wire protocol

Source code (vwt97v01.bas) and executable file 

(vwt97v01.exe) are provided



To run this program 

	* Copy pckit folder to a local disk

	* Connect a VW unit to your PC serial port

	  (To see how to assemble a VW unit, check out

	  the VW manual, page 20)

	* Modify the configuration file (vwt97.cfg) as

	  necessary (COM port, BAUD rate, receiver node

	  address). This can also be done after starting

	  up the program (<ALT>+<S>)

	* Start up the program by double-clicking the

	  file vwt97v01.exe





**************** PalmPilot demo program ************

This program is created using MetroWerks CodeWarrior. 

It demonstrates the interaction of a Palm application 

with the Virtual Wire protocol. It is designed for a

Palm application to communicate with the PC terminal 

program

Project source code is provided



To have a PalmPilot communicate with a PC

	* Setup the PC terminal program as decribed in

	  the previous section, with a node address of

	  2 (see manual, page 21, for how to program 

	  node address)

	* Load the Palm application (rfdemo.prc) to

	  a PalmPilot (using HotSync)

	* Connect the PalmPilot serial port to a VW

	  unit with node address of 1

	* Startup the application by touching on the

	  RFDemo icon
