[SPI3] Extensive testing of the new Modbus driver

[Christofer Dutz]

Hi all,

I just wanted to point out that today I’ve added an Integration Test that 
starts a python Modbus server and then runs our driver against that and tests:


  *
Modbus TCP
     *
TCP
     *
UDP
     *
TLS
  *
Modbus RTU
     *
TCP
     *
UDP
  *
Mobbus ASCII
     *
TCP
     *
UDP

Technically it would have been possible to also map a serial port, but I tried 
that in my ToddySoft Firmata driver and it was a stability nightmare.

So … just if you’re interested.
