-    # The datastores only respond to the addresses that they are initialized to
-    # Therefore, if you initialize a DataBlock to addresses from 0x00 to 0xFF,
-    # a request to 0x100 will respond with an invalid address exception.
-    # This is because many devices exhibit this kind of behavior (but not all)
-    #
-    #     block = ModbusSequentialDataBlock(0x00, [0]*0xff)
-    #
-    # Continuing, you can choose to use a sequential or a sparse DataBlock in
-    # your data context.  The difference is that the sequential has no gaps in
-    # the data while the sparse can. Once again, there are devices that exhibit
-    # both forms of behavior::
-    #
-    #     block = ModbusSparseDataBlock({0x00: 0, 0x05: 1})
-    #     block = ModbusSequentialDataBlock(0x00, [0]*5)
-    #
-    # Alternately, you can use the factory methods to initialize the DataBlocks
-    # or simply do not pass them to have them initialized to 0x00 on the full
-    # address range::
-    #
-    #     store = ModbusSlaveContext(di = ModbusSequentialDataBlock.create())
-    #     store = ModbusSlaveContext()
-    #
-    # Finally, you are allowed to use the same DataBlock reference for every
-    # table or you you may use a seperate DataBlock for each table.
-    # This depends if you would like functions to be able to access and modify
-    # the same data or not::
-    #
-    #     block = ModbusSequentialDataBlock(0x00, [0]*0xff)
-    #     store = ModbusSlaveContext(di=block, co=block, hr=block, ir=block)
-    #
-    # The server then makes use of a server context that allows the server to
-    # respond with different slave contexts for different unit ids. By default
-    # it will return the same context for every unit id supplied (broadcast
-    # mode).
-    # However, this can be overloaded by setting the single flag to False
-    # and then supplying a dictionary of unit id to context mapping::
-    #
-    #     slaves  = {
-    #         0x01: ModbusSlaveContext(...),
-    #         0x02: ModbusSlaveContext(...),

-    #     }
-    #     context = ModbusServerContext(slaves=slaves, single=False)
-    #
-    # The slave context can also be initialized in zero_mode which means that a
-    # request to address(0-7) will map to the address (0-7). The default is
-    # False which is based on section 4.4 of the specification, so address(0-7)
-    # will map to (1-8)::
