=================================================

Description
------------------------------------
Make possible to write modbus TCP and RTU master and slave.

It can be used for testing purpose : It is shipped with slave simulator and a master with a web-based hmi (ok the hmi need to be improved :).

It can also be used to create any application which need to communicate over modbus. It is a full-stack implementation and is used on "real applications".

Thanks to Python and the incredible set of existing libraries, it can fit a lot of different needs : database logging, HMI, report generation ...

modbus-tk is different from pymodbus which is another implementation of the modbus stack in python.

modbus-tk tries to limit dependencies (even if it requires pyserial for Modbus RTU).

modbus-tk has no link with tkInter. tk stands for 'testkit' or 'toolkit' depending of the way you use it.

MicroPython port by Sean Lannigan : https://gitlab.com/extel-open-source/micropython-modbus .So far it only supports RTU Master mode (i.e. no TCP and no slave mode), as this was all I needed in Sean's MicroPython application - the other modes probably wouldn't be too hard to port.
