I believe that there is some sort of problem with Taylor's "i" protocol at higher window and packet sizes. If I remember rightly, Evan should try forcing the window size below 16 (it can go to 31). I think there may be a comment to that fact in the Taylor distribution somewhere. -- Chris Lewis: _Una confibula non sat est_ Phone: Canada 613 832-0541 Latest psroff: FTP://ftp.uunet.ca/distrib/chris_lewis/psroff3.0pl17/* Latest hp2pbm: FTP://ftp.uunet.ca/distrib/chris_lewis/hp2pbm/*
