ange-ftp using binary mode

ange-ftp using binary mode

[Ken Goldman]

I have to use ange-ftp because the server I'm connecting to doesn't run 
ssh.  When I transfer, it uses binary, which does not work.  The server 
is a mainframe and likely uses ebcdic.

If I ftp from the command line in ascii mode, the file comes over to 
Windows correctly.  If I enter the commands by hand in the ange-ftp, 
setting ascii, it works.

How do I tell ange-ftp to use ascii?

I set ange-ftp-binary-file-name-regexp to "", even though the .cpp file 
wasn't in the regexp.

Here's a trace.

Are you using ange-ftp via "C-x C-f"?  If so, tell Emacs to decode the
file, as in "C-x RET c ebcdic-us RET C-x C-f whatever RET".

If you use some other command, again prefix that command with
universal-coding-system-argument ("C-x RET c") to tell it to use
EBCDIC, or whatever is right for those files.

IOW, just imagine the file was on your local disk, and do the same.
You cannot tell disk I/O to "use ascii", can you?

`ange-ftp-binary-file-name-regexp' tells, which files are to be
transferred in binary mode. "" matches ALL files. So you must set it to
a regexp, which doesn't match any file name, like "^$" (which is the
empty file name).

Best regards, Michael.

I tried this, but it still transfers in binary.

~~~~~~~~

ange-ftp-binary-file-name-regexp is a variable defined in `ange-ftp.el'.
Its value is "^$"

I tried this and it is somewhat better.  I can see the text but all the 
newline appears as \205, [ as \255 and ] as \275.

I think I simply want to tell ange-ftp to use ascii, not binary, but 
nothing I tried works.

Maybe it's not EBCDIC after all.

If it's not, it's close, as your suggestion to use
ebcdic-us made it much better.

Following up my own post, I edited ange-ftp.el and changed 'binary' to 
'ascii'.  Files now come across absolutely perfectly.

I know that's an awful hack, but it's a proof of concept.  Now, how do I 
convince ange-ftp to use ascii without editing the elisp source?

Which Emacs version are you running?

Last year, there was a bug report about ange-ftp's binary mode, see
<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=7383>. IIRC, it was about
ange-ftp always using binary mode, when your local system is MS
Windows. This is fixed meanwhile.

Chances are good, that a prerelease of Emacs 24.1 works for you out-of-the-box.

Best regards, Michael.

I looked at the bug reports, but they seem to be cases where people 
__wanted__ binary mode.  I have the opposite issue.  I always want ASCII 
mode so ftp will do the EBCDIC <-> ASCII conversion.

I'm running 23.1.1.  I won't risk a pre-release when I have a source 
code hack that works.  I'll retest when 24 goes into production.
