Marcus,
I am replying to you and the list here, I apologize for not keeping all
this on the list. Anyway, the cable has been specifically built and
tested for directly connecting two computers. It worked great recently,
then I had a hardware failure (new motherboard and fresh install of a new
OS as a result) As I rebuild, I'm changing a few things around so a
simple restore won't work here...
Thanks again,
Ben
