(feature request) MODBUS support

[limpkin]

allow user to specify 3 pins (TX/RX/DE) to present registers to the outside. these registers should then allow an eternal MODBUS master to do the same operations as #33

What is Modbus? What device uses this?
If I google I see also rs485, which is used for dmx - in.

Which is planned to be added. Maybe combined with this modbus request ?

[limpkin]

maybe yes :)
