Telnet is an application protocol and command-line client for establishing a TCP connection to a specified server and host. It provides a terminal for sending and receiving bytes. section 3.2
Use Telnet as a simple way to test socket-based servers: connect to an address, type data, and press Enter to send it. The server can observe the client connection, but must separately implement reading and writing. section 3.2 section 3.1
Connect to a local socket server
Run a server listening on localhost port 8000, then execute `telnet localhost 8000`. Telnet reports the connection, displays a cursor, and sends typed input when Enter is selected. section 3.2
telnet localhost 8000
Use the command listing to connect a Telnet client to the local test server. section 3.2
