Answer

The SendCommand can only be used for commands where the result is just a reply on the command/control connection. It seems like you're trying to download a file, but that's not possible because FTP sends the file on a separate data connection.
You're confusing the commands of an FTP console application vs. the commands of the FTP protocol. Let's say you start a DOS prompt and type the "ftp" command, and then begin entering commands at the FTP prompt, such as "ls", "cd", "get", etc. These are the human-interface commands to the FTP client application. The actual commands that get sent to the FTP server are the FTP protocol commands. These are specified in RFC 959 (https://tools.ietf.org/html/rfc959) as well as in many RFC's for FTP protocol extensions.

certainly makes sense. Thanks.
