| 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.
