            PASS <SP> <password> <CRLF>   : Specify password for authentication

            CWD  <SP> <pathname> <CRLF>   : Change working directory
            CDUP <CRLF>                   : Change working directory to parent directory

            QUIT <CRLF>                   : Disconnection

            DELE <SP> <pathname> <CRLF>   : Delete file on the server

            PWD  <CRLF>                   : Print working directory

            PASV <CRLF>                   : Enable "passive" mode for data transfer

            PORT <SP> <host-port> <CRLF>  : Enable "active" mode for data transfer


            HELP [<SP> <string>] <CRLF>   : List available commands

            NOOP <CRLF>                   : Do nothing

            (the following are commands using data transfer )

            RETR <SP> <pathname> <CRLF>   : Download file from server to client
            STOR <SP> <pathname> <CRLF>   : Upload file from client to server
            LIST [<SP> <pathname>] <CRLF> : List files in the current working directory 


Command-Reply Sequences

The server reply is defined to contain the 3-digit code, followed by Space <SP>, followed by one line of text, and terminated by the Telnet end-of-line code <CRLF>.

Example :

-> USER <SP> Username <CRLF>
<- 331 <SP> User name okay, need password. <CRLF>
-> PASS <SP> Password <CRLF>
<- 230 <SP> User logged in, proceed. <CRLF>

-> : Request command from client to server
<- : Reply from server to client
