The bimode() call is only if the *server* is running on Windows,
not for the client. On a *nix server, all file I/O is binary,
so there is no need for the binmode() call. Windoze/DOS distinguishes
between text and binary streams.

Perhaps you should stat the file handle returned by the CGI,
find out the file length and debug dump it.
Also, ensure
1. $file is a CGI variable from a field of the form
<input type=file name=file>
2. your form's content encoding is "multipart/form-data"
and not "application/x-www-form-urlencoded"
I mention (2) since perhaps that is difference between the Unix
and the 'Doze browsers. Perhaps if you get it wrong in Unix
(and are using "application/x-www-form-urlencoded") the
browser fixes it up and sends in the multi-part data anyway?!?!
