E.g. The "querymodem" script in the "querymodem" sample, the last line is

commx.writeStr(command);

You can change it to

var stream = new StringStream;
stream.write(command);
commx.write(stream);

The "stream" object contains the binary data and is sent by the "write" method.

Similarly, in the "initialize" script, the "onRXChar" event handler is

var str = this.readStr(count);
FlashPlayer.setVariable("response.text", str);
trace(str);

It can be changed to

var stream = this.read(count);
FlashPlayer.setVariable("response.text", stream.toString());
trace(stream);

The "read" method returns a stringstream object contains binary data.
