Review comment:
       Ambiguity abounds no matter how it is described. I figure that a client 
originates a connection to a listener and that a connector originates a 
connection to a server. Clients never accept connections and servers never 
originate connections. 
   Also, there was some bad code logic in these descriptions that caused the 
logs to say wrong things. An update is coming shortly.

> I have a tcp-echo server running locally through:
> podman run -d --rm --name tcpecho -p 9090:9090 quay.io/skupper/tcp-go-echo
> And I have a router configured with a tcpConnector to localhost at port 9090 
> and a tcpListener at port 9999.
> I am able to use nc (netcat) to send data to the tcp-echo directly (port 
> 9090) or through
> the router (port 9999), if I run "nc 127.0.0.1 9999" and the send the data.
> But if I run it as:  "echo abcd | nc 127.0.0.1 9999" I am not seeing a 
> response, but if 
> I use port 9090 (original port) instead of 9999 (router tcpListener), then I 
> get the
> response correctly.
