   Indeed, TCP is supposed to support "simplex" operation where data can   
   flow in only one direction.  I seem to recall some sort of ancient   
   remote job entry mechanism using that feature, but I cannot recall its   
   name, nor anything more recent which actually used the simplex   
   feature.
