on GitHub

features:

• new SerialInputOutputManager.start() method for starting ioManager thread

fixes:

• Previously recommended start action Executors.newSingleThreadExecutor().submit(ioManager) did not shutdown the executor, which caused a thread leak.
  Use new SerialInputOutputManager.start() method instead. It's still possible to use old style start, as SerialInputOutputManager continues to implement Runnable interface.
• read w/o timeout now only throws exception on connection lost. Reverted buffer to small handling from f4166f3, as there might be unkown reasons for empty response
