If you're using something like an FT232 to convert from usb to TTL on the
device side, Windows will automatically install a virtual com port driver,
and you just need to look in the device manager to see which COM port # it
set for that device. When you open the SerialPort object in Cuis, just
provide the port # as the port argument, and it should work with no issues.
