    Hello,
    can someone confirm that modbus over serial port is working on windows ?
    all my experiments led me to the thought that it is absolutely broken.
    i am using arduno as a modbus device. i tested it with qmodbus and modbus poll. works great. but when i try to use modbus examples from qt(qtserialbus/examples/serialbus/modbus/master), look like it can not send request.
    i tried release(5.6) and git version of qtserialbus and qtserialport modules with no luck.

    i am using windows 7 on virtualbox.
    arduino modbus library from here https://github.com/smarmengol/Modbus-Master-Slave-for-Arduino
    arduino sketch http://pastebin.com/FHW3B7TX

    it's me or it's really broken ?

      Hi and welcome to devnet,

      The module being pretty new, I'd recommend posting this question on the interest mailing list. You'll find there QtSerialBus's developers/maintainers. This forum is more user oriented.

          Hello Dmitry.

          Did you manage to connect to a device using modbus under windows? I faced with the same problem. Qt5.7.
