This Filter accepts packets of the type generated by
<A HREF="PacketSource">PacketSource</A> and displays the contained
value in its panel (if visible -- use the diagram element's popup menu
item to open it).
The panel has no controls -- just the displayed value, shown in red
if the last packet received was from a PacketSource.
<P>
In addition to showing the actual integer values of such packets,
the Counter will <i>count</i> packets of <i>any</i> type.
Each time it sees a packet of any type but PacketSource, it adds one
to the currently displayed value and shows it in <i>blue</i>.
Note that this is <i>not</i> independent of data received from
a packet source -- it simply counts from the last integer that arrived
(initially zero).
<P>
The Counter also demonstrates a feature added to the Weaver v3.0.
A signal is sent to all modules when the load of a configuration
is completed, and -- if it is not doing anything else -- the Counter
will illustrate this by displaying 'COMPLETE' in its panel when the
signal is received.
<P>

 <A HREF="../../Documentation/TestModules.html#Counter">Counter</A>
section in the Test Modules documentation.
