I read the javax.comm api and noticed that it is supported for Sun and Linux but not for windows. is there a standard way for Windows also? I would like to build a simle app that communicates with external handmade device via parallel port.

    Has anyone been able to work on reading/listening to parallel ports using JAVA?
    I am working on a project that listens to a parallel port and I am having a problem, big time.

    Need some advice, the only thing I have done so far is detect the port (LPT1) but I have

    Any words on this?

    Please help.
