ange-FTP and Windows NT servers

[Sebastian P. Luque]

Hi,

Trying to access the following Windows NT ftp server through
tramp/ange-FTP fails:

/anonymous@win-builder.r-project.org:/

http://win-builder.r-project.org has a brief explanation for connecting,
which says we should connect with passive ftp in binary mode (I don't
understand what this means).  The following appears in *Messages*:

Listing /anonymous@win-builder.r-project.org:/...done
Doing CD... [44 times]
 nonexistent.

and I can't get any further with debug-on-error set to t.  I can interact
with that directory from a browser (konqueror) at
ftp://win-builder.r-project.org without problems.  I'm told that the
problem seems to be that ange-FTP doesn't understand Windows NT directory
listing format.  Logging in from the shell gives:

---<---------------cut here---------------start-------------->---

Hopefully someone with experience on ange-FTP can provide some suggestions
as to what may be going on.  Thanks.

Are you using the latest Emacs version (22)? If so please send a bug report.
