The behaviour of "\n" is generally dependent on the operating-system and the output stream to which you are writing. On Unix-like systems under most circumstances it translates to '0A' as you note. The same is true for Windows-like files opened in binary mode.

When writing to Unix-like terminals in canonical mode, or to Windows-like files in text-mode it is '0D' '0A' as you require. Note, I'm using your terminology for consistency. In Perl these would be more commonly denoted as '\x0D' and '\x0A' respectively.

The previous sentence should be all the hint you need, but here it is spelled out explicitly. To force the issue regardless of operating system and nature of the output stream replace 'print "\n";' with 'print "\x0D\x0A";' and you will get what you ask for.

Whether what you ask for is what you want is another matter entirely...
