    Hello everyone,

    Here a small quick and dirty implementation of the modbus TCP protocol in B4J as a server / slave.
    Please note that this is not a complete library!
    The following limitations are:
    -Only READING (not writing) of holding registers possible by modbus master(function code 03) from 0-200
    -Example in NON gui application
    -No error code implementation (send to master), only some error info in the logs locally

    I made it just to get some data out of a raspberry pi.
