This abstract base client contains all the basic methods and handlings required to communicate via Modbus Protocol.
The packages `AMWD.Protocols.Modbus.Serial` _(in progress)_ and `AMWD.Protocols.Modbus.Tcp` have specific derived implementations to match the communication types.

The implementations over serial line (RTU and ASCII) have a minimum unit ID of one (1) referring to the specification.
This validation is _not_ implemented here due to real world experience, that some manufactures do not care about it.
