Hi!
I am developing a test tool for swedish banks to test card payment devices. This tool uses FTP to interact with a remote configuration server using an interface defined by swedish banks called PPL (Program an Parameter Download)
Such a PPL server does not support the FTP SYST command.
Problem is i use the TIdFTP component in my application. And I have yet to find out how to disable the TIdFTP Indy component from sending the FTP SYST command.
Is there a way to disable the TIdFTP component from sending the FTP SYST command?
I am currently using XE2 but am upgrading to XE7.
Regards, Kjell-Olov

When I connect to some WSFTP-based servers, for example, I see FEAT failing
as unsupported. It is just the nature of the beast (FTP). FTP clients use
SYST and FEAT to discover a server's capabilities so they can tailor subsequent
commands accordingly, that's all.

OK, I see. Well, that is not an option. Tanks anyhow.

I am developing a test tool interfacing a server providing configuration files. This server interface is based on a very limited set of FTP commands and SYST is not one of them. Thus test operators are annoyed of having the SYST command showing up in the log although the server interface specifies it shall not be used. It does not cause and error, only confusion. We can live with it. In worst case I may have to intercept this command locally and fake a response, thus hiding it from the server.

No. You would have to alter Indy's source code and recompile it.
Why is this a problem? Most FTP client apps issue SYST, and TIdFTP accounts
for the possibility that SYST may fail on some servers.
