A telnet client for the DS. It is a user command and a TCP/IP protocol used to access remote computers.
Telnet is an old network communications protocol but one that often features in embedded hardware (although SSH has now taken over for the better stuff) and also has some long running games known as MUDs.
Make a text file at /DSTELNET/config.cfg with the URL or IP of the telnet server you wish to connect to.
- This version can connect to a telnet server of your choice.
