    Cameron,
    Thanks for sharing that link. Can you elaborate on the protocol you chose?
    I'm guessing its an open spec. If so, I would be interested in evaluating it
    as a base for my own drivers.

    Helmut,
    After searching the net today, and following Cameron's link, I see there is Linux
    OPC capability, server and client. Still, Its seems to be a cumbersome option that
    would only be useful if paired with at least one Windows machine running OPC
    servers for the hardware interface. For some, this might be a feasible option.

    I like to code everything myself in tcl, so I can be in full control of my
    projects. I've drifted away from relying on proprietary software as it almost
    always lets me down for one reason or another.

    Since tcl is such a great language for industrial control use, It would be great
    to discuss protocol and API options so that colaboration in this field of
    tcl programming can be developed. I'd prefer to point interested programmers
    to a development resource, like a wiki, rather than blabber on about how I
    dislike the current state of Windows based solutions. This is an area of tcl
    that needs some momentum.

    I look forward to discussing this further.
