Well the easiest for me to use was a graph-link cable. With that and a few
other components you can use it to also communicate with a computer via the
serial port. I am not saying this is a great design just easy and
convenient. And yes it is direct line of site so unless you have some
binoculars to spot the receiver, you farthest distance you can be is in
eyesight range. Nothing special, just a neat idea.
