Tramp using plink - password not recognized

[calbloke@yahoo.com (andrew)]

I'm having some problems getting connected using Tramp 2.0.15 and
plink.

I'm running  the windows port of emacs version 21.2.1 under win 2k

Below is the output from the debug buffer.

I can get plink to work in a command window  but  when I try through
emacs, I am prompted for the password 4 times  before the connection
process fails

I had slightly better luck with an older version of tramp in that  the
password was accepted but  the remote login script  then prompted for
input of a variable which caused some problems - that is when I
switched to the latest version of tramp which gives me the results
mentioned above.

Any help appreciated

Thankyou
