In another thread (http://forums.parallax.com/showthread.php/138578) I showed how to connect this 17" touchscreen monitor
using it's USB output and a VNC2 chip.

But now, I've got an even easier way... Just using a transistor and a resistor (Phil's idea) to convert the RS232 output
of the touchscreen monitor (DB9 connector) and adapt it to the mini-DIN-6 mouse (or keyboard) input of the Propeller
Demo Board.

Here's a photo of the little adapter (just a 100 Ohm resistor and a 2n3904 NPN transistor):

I'm only using 2 wires from the DB9 and two from the mini-DIN-6 cable.
Here's code that shows the "reports" from the touchscreen (translation is in that other thread):
