    I resolved the COM port issue by un-installing all forms of Java on my computer.

    Then going to and getting the latest version for whatever system I was running (32 or 64 bit).

    It's only mentioned in a few places I've seen but Glediator is a java program and to allow it to communicate by serial you need to intall RXTX for java.
    Follow the install instructions in the text file for whatever bit system you are running.

    Good luck

    Hey Ninten, were you on mac by any chance? I'd love some help installing RXTX as I can't seem to get it working.

    Furthest I got required unarchiving a stuffit archive which is apparently really old.
