title: public Modbus server
body: <p>I've been programming a Modbus Client through TCP and I think I'm finally done but I'd like to test it in real life scenarios and that's why I'm coming here:</p>
  
  <p>¿Is there any Modbus Server available online? I mean, any kind of modbus server even though it servers only trash bytes is OK.</p>
  
  <p>¿Any ideas?</p>
