    Question RS485 communication in VB

    Has anyone ever had to work with RS485 (as opposed to normal RS232) communication in VB? I have seen it done in C++, even tried it myself, but did not think of using VB for speed reasons.
    Any takers
    for (int i = 0;i < y3k; i++)
    {
    MakeMeSmarter (andMoreTolerant);
    }

    My thoughts:

    RS232 and RS485 are hardware specifications - the software protocol is independant of what wiring and voltages you have.

    I haven't yet come across a PC with an RS485 port, but you can get hardware converters to plug in to the back of your machine.

    What kind of speed are you intending to run your comms at that you think VB won't support? It's really down to the hardware (the comms driver and your CPU, disk access and bus speeds) rather than the programming language.

    Tris.
