Afdhal Atiff Tan / ModbusSlave232

This library meant to allow mbed boards (tested on F401RE) to act as modbus slave. I don't own this work, I just made some simple modifications so that it runs on mbed. My modification were labeled with "afdhal". Summary: Modified modbus Arduino library for mbed. See readme for more details. Feel free to use it as you want. Special thanks to the original authors.
