FW: cURL problem with ascii download from tandem

This is an expansion from the previous question
(that was posted from my home address, where i didn't
have all the information available) and a private mail
with Daniel Stenberg.

On his request I posted it to the group...)

Original post:

A transfer with a tandem system consistently fails:
Without the -B it works, but it is an ASCII file and
and the tandem has a rich filesystem (ascii files are not
a stream of bytes with linefeed inserted).

Binary download

curl -u fss.ftpcoins:test!! ftp://tandem.xtra.nl/$DATA.PCEOE.PCG0049 -o t.txt
  % Total % Received % Xferd Average Speed Time Curr.
                                 Dload Upload Total Current Left Speed
100 69632 100 69632 0 0 34420 0 0:00:02 0:00:02 0:00:00 65252

(but the file is useless)

Ascii download:

curl -u fss.ftpcoins:test!! ftp://tandem.xtra.nl/$DATA.PCEOE.PCG0049 -o t.txt -B
  % Total % Received % Xferd Average Speed Time Curr.
                                 Dload Upload Total Current Left Speed

rl: (18) Received only partial file

another one with -v to show you intermediate results:

curl -u fss.ftpcoins:test!! ftp://tandem.xtra.nl/$DATA.PCEOE.PCG0049 -o t.txt -B

just ftp from NT does work:

The initially mentioned 69632 bytes is the tandem ascii format then and the
65450 bytes is in NT format?

It would also be interesting to see what the commands the NT client issues,
as can be seen if you enter 'debug' in the client before you do open.

<end of conversation>

Yep the file is complete the size difference is probably because of the
file structure information within the file which is not present on
unix/Windows system. There a file is just a bunch of unstructured bytes.
Tandem and VMS (and others that have record structured files) store record
lengths,
index data for index sequential files etc within the file.

upon request of daniel I added the debug output of a succesfull transfer
(Windows NT
native ftp client) below.

And a session without pasv
