That's a significant bug, thank you.

Apparently the server is trying to negotiate with the client.

I tried to answer properly, to no avail.

Then I tried to use Net::Telnet to do it and then pretend to be an
ordinary socket. May work later, but not yet.

Hmm. How hard would it be to write a little program (say, a tiny
text adventure) to which I could connect via telnet? I've never
written anything like a telnet server, but it doesn't seem hard
if we skip the "real" functionality of it. Am I wrong?

Thanks,
Hal
