I would be very grateful if you could describe in details how one can make WinSCP plugin to interact with server using Plink? Many users would love to have interactive winscp plugin and you might help many of us. There are quite a few tasks that involve keyboard interactions.... for which one would need to run Putty, and that is the main pitfall of winscp plugin (it just freezes)
That's nothing about WinSCP plugin. Just that you can start plink console terminal from FAR window. Or maybe you can replace putty with plink in WinSCP configuration so that plugin's Open in PuTTY command starts plink.
