Thanks for this link. The mentioning of packet radio raised my
interest and I was not aware of the Stanford experiments. Yet I am
somehow puzzled as packet radio used AX.25. Thus whilst I understand
the packet transmission of data was proven, is packet radio really
that closely related to TCP/IP? <br class="">
Kindest regards,<br class="">
