Datasheet

On Windows you can use PuTTY (http://adafru.it/aWh) as a serial console. Download and run PuTTY, then configure it for a
Connection type of Serial as shown below on the right. The Serial line should be set to the COM port you found for the USB
serial converter in device manager (shown on the left), in this case COM5. Speed should be set to 9600 baud.
Click open and you should see an empty terminal screen appear. Try typing a message and you should see what you type
echoed back to you, like below:
If you don't see anything, make sure you've connected the D0 pin to the D1 pin on the FT232H board.
Also make sure you're using the right COM port for the FT232H device. Try unplugging any other USB to serial converter
(including development boards like Arduinos!) and only connecting the FT232H board to make sure you can find its COM port in
device manager.
Mac OSX
On a Mac you can use a few included terminal commands to list serial ports and connect to a serial port to test the loopback
connection.
