/*
This class is a basic extension of the Applet class. It would generally
be used as the main class with a Java browser or the AppletViewer. But
an instance can be added to a subclass of Container. To use this applet
with a browser or the AppletViewer, create an html file with the
following code:
CSocketClient
You can add controls to CSocketClient with Cafe Studio.
(Menus can be added only to subclasses of Frame.)
