    16 <section><title>Description</title> <p>The TCP example is a client for the

    17 simple Echo protocol. A server implementing this protocol, defined in RFC862,

    18 simply listens on port 7 for incoming data, and returns it to the client.

    19 EchoClientEngine is a DLL that implements the engine component of the client.

    20 It contains active object classes that encapsulate reading, writing and connect

    21 operations. The related example project <xref href="GUID-2274DE87-8D6B-5376-A9AE-03ABE4DEE495.dita">EchoClientUI</xref> provides

    22 a GUI interface to drive the engine. </p> </section>
