There are some manufacturers who would use the
hardware control leads
to communicate information (more than just for flow-control). Was it
maybe the programming interface for Motorola radios?
Let's not forget the secondary channel interface as well as the
peculiar setups of modems with low-speed "reverse" channels. Then
there are the synchronous modems...
Simple point-to-point async is simple by comparison!
