-------------------------------------------------------------------------------------------------------------
----Release version 1.2.1 -------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------------------
This version contains some improvements and some bug fixes. Also, the RXTX library is currently supported.
	NEWS:
	* IMPORTANT! the RXTX library is now supported! You should invoke SerialUtils.setSerialPortFactory(new SerialPortFactoryRXTX()); before you'll have created a master or a slave.
	* added checking if jssc library is available
	* fixed potential bug with reading of byte array.
	* avoiding some NullPointerException exceptions.
	* IMPORTANT! fixed bug with flushing of output buffers.
	* modbus rtu master is now able to connect via tcp socket(in case of rs232/rs485 to wifi adapters).
	* added abstraction of concrete serial port implementation.
-------------------------------------------------------------------------------------------------------------
----Release version 1.2 -------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------------------
This version contains some improvements.
	NEWS:
	* Added extended logging.
	* Auto increment of transaction id is currently supported. see Modbus.setAutoIncrementTransactionId.
	* Refactoring.
