The Dragon's P3IO has two serial ports that the regular P3IOs do not, and one of these serial ports
is used to communicate with the card readers. Note that these are actual serial ports driven
directly by the P3IO microcontroller, these are NOT just passed through to the motherboard like the
proprietary COM1 and COM2 connectors. Unicorn Tail intercepts serial port IO commands being sent to
the P3IO and redirects them to COM2 instead, since COM2 is unused on SD cabinets (on HD cabinets it
connects to a second ACIO bus which drives the extra lighting glitz like the light spikes and maybe
the LED strip).

Unicorn Tail intercepts serial port IO commands being sent to the P3IO and redirects them to a
COM4 in Windows instead, where two readers can be connected via the motherboard's RS232 port or

## COM Port Setup
Using Device Manager in Windows, ensure the following COM ports are connected and setup.
COM1: EXTIO
COM4: Two readers
Windows is often poor about saving the COM port number, so ewf commit (if applicable) and
