Gangplank is a Computer Mediated Communication (CMC) system (or "chat server") which supports real-time communication between users, currently using a text-based user interface. It runs as an Internet server which implements the standard telnet protocol, so no special client program is necessary for users. Server-side processing provides input editing/history and terminal- handling features over the telnet connection for standard ANSI terminals. This code has been in production use on a private server since early 1993. This single-process server is fast, efficient and stable.
