QSR Serial port oddity

This isn't a critical problem, but I noticed that when I
leave my QSR connected to my PC's serial port, and switch
to MIDI IN/OUT on the QSR, the serial port's upper 4bits
start going nuts. This isn't really a problem, however,
because Windows95 autodetects modems on serial ports,
if the QSR is on and in MIDI mode when Windows95 boots,
it locks up, then the machine resets itself. If I put
the QSR in Serial mode or turn it off while Windows boots,
everything is fine. Just a very weird situation. Wonder
if anyone else seen similar behavior on the QSR serial jack.
