Thanks Corion
Setting binmode would do it, but I'm trying to write some cleaner code and use the content_file parameter
I've changed my post call to 
my $response = $ua->post(
    $url, 
    ':content_file'  => '.\test.gz',
    Content_Type => 'form-data',
    Content => [
    userid           => 'USERID',
    password         => 'PASSWORD',
    recordlength     => '',
    recordterminator => 'NONE',
    remotefilename   => 'REMOTE_FILENAME'
    ]    );

However, I'm not getting the test.gz file written out. I figure I'm doing (or not doing) something stupid, but I'm not seeing it.
So I'm apprealing to the monks again to help me past my stupidity.
Thanks for you help, though.
