Determine percentage of a file that has been ftp’d from client to server

I want to ftp a large file from a client to a server, using their IP addresses. While the file is transferring, I would like to determine how many bytes have been received by the server. I then would like to use this information to determine in real-time the percentage of the file that has been transferred to the server.

Any recommendations as to the ftp command syntax to achieve this?
