Description
Network tools can implement Telnet protocol handling through a small C library.
This library is useful for developers maintaining clients, servers, embedded tools, or compatibility software that still needs Telnet. It does not provide a full terminal client by itself; another program uses it to negotiate and process Telnet sessions.
Telnet is commonly plaintext and can expose credentials or commands on the network. Prefer encrypted protocols such as SSH unless a legacy system specifically requires Telnet.
