         Re:   Physical transporter driver specification

         Attached is a preliminary version of the physical transporter
         driver specification.  A couple of the sections are not
         completely filled out.  However, it contains most everything
         I wanted to say.

         Some paragraphs are marked with "****" or "????".   These
         indicate ideas that I have been considering or were proposed
         that are contrary to the specification.  They mainly involve
         setup receive interrupts.  I feel it is better to have the
         driver only call the user for a receive indication and not
         for a setup complete.  If you have an opinion and a
         justification for it I would appreciate it with your written
         comments.

         Please, return your comments to me as soon as possible.
