I've tried a lot of ports for telnet, and none of them seem to work.
Whenever I connect, it doesn't ask for a username or password (with the telnet client built in to Windows) and PuTTY doesn't even connect to the server.
If it helps at all, I have gotten it to work once in the built in client, but it didn't respond to the keyboard.
DCC chat works.
I'm running eggdrop v1.6.18+SSL, on FreeBSD 5.3-RELEASE.
