Requirements:
-------------

        Microtronix MicroPad version 1.43 (or higher)
        WinView for Networks ver 2.3 (or higher)

Setup:
------

        Follow the instructions for the setup of the MicroPad as detailed
in the documentation provided by Micrtronix. In addition, the following
steps should be followed to properly configure the ports. In the example
listed below, the remote client was connected to port 1, while the WinView
host was connected to port 2. Port 0 was used for configuration. Comments
are listed after each line in between the /* and */.
