FTP Session
Figure 15.11 is a screen capture of an FTP session with the relay. The FTP client
used for this example is included with the Windows operating system and acces-
sible through a command prompt window. The operator connects to the relay,
moves to the SETTINGS directory, and collects the PORT 5 settings. Figure 15.11
shows a portion of the PORT 5 settings in the SET_P5.TXT file.
