  Interesting ... to remember that PEP modems like the Telebit
Trailblazer put out essentially half duplex packets, with fast
turnaround to simulate full duplex. Now if only the modems will keep
silent when there no data to send, (except perhaps for a keep alive
packet every second or so) then ... what is the difference if any at
all between these modems and human conversation ?

  Will the (now being discussed) modem-service-charge apply in that
case ?  :-)
