  RXTX License v 2.1 - LGPL v 2.1 + Linking Over Controlled Interface.
  RXTX is a native interface to serial ports in java.
  Copyright 1997-2007 by Trent Jarvi tjarvi@qbang.org and others who
  actually wrote it.  See individual source files for more information.

  This library is free software; you can redistribute it and/or

  License as published by the Free Software Foundation; either
  version 2.1 of the License, or (at your option) any later version.

  Lesser General Public License for more details.

  An executable that contains no derivative of any portion of RXTX, but
  is designed to work with RXTX by being dynamically linked with it,
  is considered a "work that uses the Library" subject to the terms and
  conditions of the GNU Lesser General Public License.

  The following has been added to the RXTX License to remove
  any confusion about linking to RXTX.   We want to allow in part what
  section 5, paragraph 2 of the LGPL does not permit in the special
  case of linking over a controlled interface.  The intent is to add a
  Java Specification Request or standards body defined interface in the
  future as another exception but one is not currently available.

  As a special exception, the copyright holders of RXTX give you
  permission to link RXTX with independent modules that communicate with
  RXTX solely through the Sun Microsytems CommAPI interface version 2,
  regardless of the license terms of these independent modules, and to copy
  and distribute the resulting combined work under terms of your choice,
  provided that every copy of the combined work is accompanied by a complete
  copy of the source code of RXTX (the version of RXTX used to produce the
  combined work), being distributed under the terms of the GNU Lesser General
  Public License plus this exception.  An independent module is a
  module which is not derived from or based on RXTX.

  Note that people who make modified versions of RXTX are not obligated
  to grant this special exception for their modified versions; it is
  their choice whether to do so.  The GNU Lesser General Public License
  gives permission to release a modified version without this exception; this
  exception also makes it possible to release a modified version which
  carries forward this exception.
