Enable PTY ?

Hi,
I must connect to a server via putty using -t option ('enable PTY').
Connecting to this server does not work, I guess because I did not pass -t option.
How can I pass this option to WinSCP?
Thanks!

PTY is mutually exclusive to SFTP/SCP protocols.
Why do you need PTY to connect?

"Why do you need PTY to connect?"
I tried to connect to the server with putty and without '-t', but it does not work. The option -t is mandatory for this server.
No chance to add this option in WinSCP ? Or do you know an alternative ?
Thanks.

Once again, PTY is mutually exclusive to SFTP/SCP protocols. In other words, no SFTP nor SCP client can ever work with a server that does not allow connections without a terminal emulation. It has nothing to do with WinSCP.

If you want us to help you further, please provide more details than "it does not work".

Here is the error I get when I ommit -t:

But what problem do you get with WinSCP?
