An extensible vt100 terminal emulator for Common Lisp
From the README:
This is an extensible telnet/vt100 screen-scraper for lisp. By rendering unreadable vt100 control sequences into an array of strings (lines), It allows you to interact with a character-based menu interface and keep your sanity.
How to get it
