The Dongles that I have taken apart consist of nothing more than a few
transistors in series to provide a delay for the signal to be fed back to
the computer.  These operate so fast that a machine language routine is
necessary to read them.  Just look for a machine language routine
somewhere near the beginning of the program that outputs to the cassette
port(most use the cassette port) and then reads back from the cassette
port without doing any data I/O.
