SENDPORT (Specify Whether to Sends a PORT Subcommand)

The SENDPORT i5/OS^® FTP client subcommand specifies whether to send a PORT subcommand to the FTP server when you transfer a data or issue the DIR and LS subcommands.

SENDPOrt [ 0 | 1 ]

If there is no parameter, SENDPORT works like a toggle switch. The SENDPORT value changes from 1 (ON) to 0 (OFF) or from 0 to 1.

When there is a parameter, the valid values are:

0: Do not send a PORT subcommand.
1: Send a PORT subcommand. This is the default.

Notes:

Use SENDPORT only when you cannot establish a connection to the FTP server without it. The indiscriminate use of SENDPORT might result in errors.
You might find it useful to not send the PORT subcommand to those systems that ignore PORT subcommands because they indicate that they have accepted the command.
The FTP client does not send the PORT subcommand when the SENDPASV option is ON.
