/**
 * The default handler used just during a "connect" for a Channel when attempting
 * to bind into an SMSC.  The reason is that some handler must be added to create
 * a channel and then replaced before the actual "bind" is attempted.  This
 * handler basically does nothing.  Until a "bind" request is received by the SMSC,
 * nothing should actually be received so its safe to have a handler that does
 * nothing.
