You should not (ab)use a telnet client for anything but to connect to something that implements the telnet protocol (which is rare these days). If you want to troubleshoot other protocols using a generic, protocol- neutral connection, you should use a tool like netcat/nc (which has several implementations included in Debian) or socat (which has more features, but can also be used for this purpose), or similar. -- Jan Claeys (please don't CC me when replying to the list)
