tramp (2.1.15-pre); Cannot edit remote VMS file

[Ingersoll, Nelson]

Enter your bug report in this message, including as much detail
as you possibly can about the problem, what you did to cause it
and what the local and remote machines are.

If you can give a simple set of instructions to make this bug
happen reliably, please include those.  Thank you for helping
kill bugs in Tramp.

Another useful thing to do is to put

  (setq tramp-verbose 8)

in the ~/.emacs file and to repeat the bug.  Then, include the
contents of the *tramp/foo* buffer and the *debug tramp/foo*
buffer in your bug report.

--bug report follows this line--


Cannot open and edit a text file, using FTP, on a remote VMS system.
All I get is a blank/empty buffer.  This is the case after issuing the
'tramp-unload-tramp' command.

Under Tramp v2.0.57 running under "GNU Emacs 22.2.1
(i386-mingw-nt5.1.2600) of 2008-03-26 on RELEASE" I am able to do a
tramp-unload-tramp and then open and edit a text file on a remote VMS
system.


This problem has been reported before.  How can I help troubleshoot and
resolve this issue.

Regards, 
Nelson Ingersoll
