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,
