App Synopsis:       This app will appear to your HP41C/CV/CX as an HP 82143A printer
                    when using Diego Diaz's USB-45 HP41 interface or Meindert Kuiprs's
                    TULIP4041 interface.  As long as the interface is properly 
                    connected, and remains connected, your HP41C/CV/CX will continue 
                    to see it as the available printer.
                    
This app is very simple and extremely intuitive but here are some basic instructions:

1.  Plug the USB-41/TULIP4041 interface into a port on the back of your HP41
    - turn the HP41 off and on again to be sure the serial port registers with your Mac
    
2.  Fire up the HP41SerialReader application
