UNIX DOS perl question

I have a problem with wriing out a text file. I am reading a text file
created on unix. I
chomp the line, do some stuff, and basically write the same line out
again.

However I am running perl on windows and perl wants to write out a CR
LF instead of just
a good old UNIX LF.

$some_string = "fred";
print "$some_string\n";

in HEX get F R E D 0D 0A

or if I write

$some_string = "fred";
print "$some_string\r";

in HEX get F R E D 0D

or

$some_string = "fred";
print "$some_string\n";

in HEX get F R E D 0D 0A

What I want ....is..

in HEX get F R E D 0A

How do I do it..

You need to put the output filehandle into binary mode, or at least
not crlf mode.

Actually the true story is rather scary but to manipulate ASCII Unix
text on Windows you can get away simply using binmode(*STDOUT) which
is wrong but works.
