To telnet or to netcat... that's the question

[NOSpaze]

Hi. If I do:

        # telnet 127.0.0.1 5038
        
        Trying 127.0.0.1...
        Connected to localhost.localdomain (127.0.0.1).
        Escape character is '^]'.
        Asterisk Call Manager/1.0
        
        Action: Login
        ActionID: 1
        Username: youwanna
        Secret: uwanna
        
... And asterisk responds:

        == Manager 'youwanna' logged on from 127.0.0.1

But if I use nc and do...

        # nc 127.0.0.1 5038 << EOF
        > Action: Login
        > ActionID: 1
        > Username: youwanna
        > Secret: uwanna
        > 
        > EOF
        Asterisk Call Manager/1.0
        
... Asterisk responds:

        == Connect attempt from '127.0.0.1' unable to authenticate
        
Notice the TEXT is EXACTLY THE SAME (pasted in both cases) tried 762753 times or something less. Tcp port.
Why is that difference? Is nc sending a different string sequence or what?

TIA...
