Lyskom

High Quality Content by WIKIPEDIA articles! LysKOM is a KOM-based conferencing system developed by the Lysator Academic Computer Society at Linköping University and Linköping Institute of Technology. It can be seen as a cross between news and e-mail, but with the presence and speed of IRC or IM-networks. The most common client is the LysKOM Emacs Lisp Client, but among others a WWW-based client also exists. The server and most clients are released under the terms of the GNU General Public License, and thus free software. The LysKOM protocol uses port 4894.
