Added a telnet section

  There's no use for a password on the -u switch, but a blank one will make

  curl ask for one and you already entered the real password to kauth.

TELNET

  The curl telnet support is basic and very easy to use. Curl passes all data

  passed to it on stdin to the remote server. Connect to a remote telnet

  server using a command line similar to:

        curl telnet://remote.server.com

  And enter the data to pass to the server on stdin. The result will be sent

  stdout or to the file you specify with -o.

  You might want the -N/--no-buffer option to switch off the buffered output

  for slow connections or if the output from the remote site is slow and/or

  without newlines.

  NOTE: the telnet protocol does not specify any way to login with a specified

  user and password and thus curl can't do that automatically. To do that, you

  need to track when the login prompt is received and send the username and

  password accordingly.

MAILING LIST

  We have an open mailing list to discuss curl, its development and things
