At what particular moment did you expect the "transfer" to end? A telnet
server is usually around always and libcurl will just hang on to it... You
need to return something in your write or progress callback to force it to
abort.

Telnet is a bit of an outsider in the libcurl community of protocols.

That is an old beast. I'd advice you to upgrade!
