7-5 Using FTP Commands
This section describes the FTP commands which the host computer (FTP cli-
ent) can send to the Ethernet Unit’s FTP server. The descriptions should also
apply to most UNIX workstations, but slight differences may arise. Refer to
your workstation’s operation manuals for details.
7-5-1 Table of Commands
The FTP commands which can be sent to the Ethernet Unit are listed in the
following table.
• The Ethernet Unit is considered to be the remote host and the host com-
puter (FTP client) is considered to be the local host.
• A remote file is a file on the Memory Card or in EM File Memory in the
CPU Unit. A local file is one in the host computer (FTP client).
• The parent directory is the directory one above the working directory.
