Yes.

And that's what I don't understand. Tramp shall NOT send PS1="#$" (these
days, it sends PS1=\#\$ ). Could you, please, have a look in tramp.el,
and search for PS1= (just these 4 characters). I did it also, and there
was no evidence, that double apostrophes are sent - this is the problem.

Have you used "plinkx" as hostname? You shouldn't, plinkx is just a
method. Your remote file name must be
"/plinkx:sessionname:/path". However, I'm not sure whether Tramp is able
to handle spaces etc in session names correctly.

That's the idea of plinkx! From the Tramp manual:

| `plinkx'
|      Another method using PuTTY on Windows.  Instead of host names, it
|      expects PuTTY session names, calling `plink -load SESSION -t"'.

Strange. That shall work. Were you prompted for the password? And did
you reply with the correct password?
