[jira] Commented: (FTPSERVER-184) IODataConnection ASCII mode does not work as expected.

["Niklas Gustavsson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FTPSERVER-184?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12645557#action_12645557 ] 

Niklas Gustavsson commented on FTPSERVER-184:
---------------------------------------------

RFC 959 does specify the following:
            In accordance with the NVT standard, the <CRLF> sequence
            should be used where necessary to denote the end of a line
            of text.  (See the discussion of file structure at the end
            of the Section on Data Representation and Storage.)

So, I think we're doing the right thing.

> New lines in files sent in ASCII mode   are transformed into /r/n  no matter what platform the ftp server is running on.  But if I'm not wrong, the new EOL should be equal to "line.separator" . If ASCII mode is going to be supported, this ought to be changed.
