title: Java modbus rtu slave
body: <p>I'm trying to develop a modbus rtu slave app. I've tried to use: j2mod, jamod, modbus4j, jmodbus. Non of them is working as I wanted to. I've googled for some examples but there is a lack of modbus rtu slave.</p>
  
  <p>Could you please provide any links/codes/suggestions ?</p>
