Plink does not allow to overwrite all options via the command line,
indeed. But the following seems to work:

plink -t -l user host TERM=dumb /bin/sh

The patch below introduces a new method "plinkx". This shall work also
with your "xterm-configured" sessions.

Could you, please, report whether it works for you? I'll commit it
then to CVS.

One possibility could be to let the user edit the connection
properties interactively. Something like `gnus-server-edit-server' in
Gnus' *Server* buffer.

The problem might be that Tramp trust those values blindly. In case
there is something wrong, there might be errors nobody can catch.

I'll play a little bit with the code in order to see whether it can be
implemented simply. But it will take some time; I'll be offline
starting end of next week, because I must go for vacations. Order from
my wife :-)

I've tried this approach some months ago, I don't remember why I gave
up. Maybe I find some comments about the reason; I'll let you know.

Best regards, Michael.
