The second incantation is typically used for Microsoft Exchange servers. Note the -crlf option, which tells s_client to send \r\n line endings. If the wrong line ending is used for a server, the symptom is that the server will not respond to any commands. It will only sit there and wait for further input, while you are staring at a blank responses or blank lines in your telnet session.
