z/VM V5R4.0 TCP/IP User's Guide
SC24-6127-04 

When you enter an FTP command, TCP/IP displays the sequence of subcommands, if any, that are sent to the foreign host's FTP server. In addition, the subcommand's response is also displayed as a reply code. These replies ensure the synchronization of requests and actions during file transfer, and guarantee that you always know the state of the foreign host's FTP server. The descriptions of the possible reply codes are listed in Table 8.

Note:

In general, the reply code descriptions below will not match the messages received from a foreign host, since reply message text will vary from one server implementation to another. The following descriptions are intended to provide an explanation of the reply codes themselves.
