 Creating a netcat server would also work as long as you disable line buffering
 and terminal echo on the commandline via `stty`:
-`$ stty -icanon -echo; ncat localhost 3000; stty icanon echo`
+`$ stty -icanon -echo; ncat localhost 2300; stty icanon echo`

+Or by using netcat's `-t` option: `$ ncat -t localhost 2300`
 
 Creating a streaming http 1.1 server than runs in the terminal is possible by
 curling it with special arguments: `$ curl -sSNT. localhost:8080`.
