I think that information should be included in RFC959:
<a href="http://www.w3.org/Protocols/rfc959/">FILE TRANSFER PROTOCOL (FTP)</a> (Look for reply codes in section 4. File Transfer Functions)
Also, have a look at RFC3659:
<a href="http://www.networksorcery.com/enp/rfc/rfc3659.txt">Extensions to FTP</a>
