    I have a scheduled fix prepared for release and review by SiI monday
    morning 9AM Pacific time. Once it is cleared by SiI, it will be released
    out to the masses.

    I can only chortle over the issue of how attempts to replace me, and me
    trying to escape the indenture servant slave of maintainership yet still
    bound after nearly 6 years.

    Will attempt to address the mod15b phy issues

    Cheers,
