    Telnet users:

    Other operation system users (UNIX, Windows, Mac, etc.) can join the chat room by running telnet to connect to the chat server at port 6912 and following the instructions echoed to their terminal. Note that characters are not echoed to their terminal, so they may want to turn on local echo, except that other messages may appear to display in the middle of their typing, so "typing blind" may be more visually appealing. For Windows and UNIX users the following command connects to a chat server named


    It is recommended to run a chat server on a system with a permanently assigned hostname or IP address that others can find, and that it is always running so others can connect. The port number can be changed from the default of 6912 on the command line of both the server and the client programs, and the entry of port number, hostname, or all settings for the client can be specified in a file such as file.ini

    where file.ini contains the following lines:


    Microsoft Windows, WINSOCK 1.1 compliant connection to internet. Optional browser to connect to chat server at same port (default 6912) to check status of connections.


    Slow connections can cause disconnects if client isn't able to respond within 15 seconds. The first 16 connected users can chat with each other, and the following users can chat to the first 16 connected users. Users connected after the first 16 will only see their own messages sent, so the chat room is effectively limited to 16 users due to the client software.
