How to Program a Telnet Client
Telnet is short for teletype network and is a protocol for communications between computers. Many telnet programs exist to allow users to connect from one computer to another over a network. Telnet, although once popular, is not used often anymore because it is not secure. Instead, SSH (secure shell) is used when communicating between two systems in a text mode. The benefit of telnet is that it's very simple and allows for manipulation of files, permissions changes and commands to be done remotely to a system.

Test the connection. Save the client session and give it a name. Choose the saved session and verify that it connects to the remote computer. If unsuccessful, either the data entered is incorrectly, the network connection is not active or telnet services may be turned off on the remote computer. Telnet services often are turned off for security reasons.
