     42  * The <code>ObexTransport</code> interface defines the underlying transport

     45  * platform, Irda). This interface provides an abstract layer to be used by the
     46  * <code>ObexConnection</code>. Each kind of medium shall have its own
     47  * implementation to wrap and follow the same interface.

     53  * a string while the TCP medium usually from a socket.
