How can I read a binary file?

Question

In my AIR application, I'm trying to read a binary file and then post it via an HTTPService to a remote ColdFusion component that accepts a "binary" type argument.  The result of the post is always:
The FILEOBJ argument passed to the addFile function is not of type binary.
Here is how I'm reading the file in Flex, where fileObj is of type File:
var fs : FileStream = new FileStream();
var bytes : ByteArray = new ByteArray();
fs.open(fileObj, FileMode.READ);
fs.readBytes(bytes, 0, fs.bytesAvailable);
fs.close();
I then pass "bytes" as the parameter to my HTTPService's send call, like so:
var params : Object = {method : "addFile", fileObject : bytes};
service.send(params);
When I debug, bytes contains the correct file size.  Is it not in binary form?  I've tried several other suggestions, but with the same result, so would appreciate any help.
Thanks!

One more step...
short are U16 integer
double are double precision float
bool seem to be 2 bytes (= U16)
char are string (variable length)
rgb are U16 integer, with high order byte = 0
rect should be 4 x U16 (top, left, bottom, right)
