A groovy libmodbus
==================

Overview
========

libmodbus is a free software library to send/receive data with a

serial port or an Ethernet connection.

The functions included in the library have been derived from the
Modicon Modbus Protocol Reference Guide which can be obtained from
Schneider at www.schneiderautomation.com.

The license of libmodbus is LGPL v3.
The licence of programs in the tests directory is GPL v3.

Installation
============

WARNING, don't use the two build systems at the same time.

With autotools
--------------
The shell commands are './configure; make; make install'.

With Waf
--------
The build system is Waf (http://code.google.com/p/waf), the shell commandes are:
$ ./waf configure
$ ./waf build
$ sudo ./waf install

or 'waf' if you use a global Waf script.

The sources are built in the 'build' directory at the root of the
project source files.


Testing
=======

Some testing programs are provided in the tests directory, you can
freely edit the source code to fit your needs (it's Free Sofware :).

See tests/README for a description of each program.
