Hi
 On my Poly88, the same serial chip is used for both the cassette and
the serial port. The cassette used the serial chip in a synchronous
mode and the serial in async.
 I made some minor changes to the setup and use most of the cassette
code to save tape programs to the PC through the serial port.
Other than being ascync, the data looks just like the cassette data.
