To test your UART port you need the following:

- a cable to connect your DS to a PC,
- a PC,
- and your DSerial with the firmware uploaded (See previous paragraph)

The cable is really easy to make. See the schematic below:



Start Terminal.exe (originally from: http://bray.velenje.cx/avr/terminal/)make the following settings:
Baud rate = 9600
Data bits = 8
Parity = None
Stop bits = 1

Then select the right COM Port and press "Connect"

Now on the DS press R to boot the firmware. (Please note that newer dserial software automatically boots the firmware)
Then press X to set the baud rate to 9600.
Press A to send a test string to your PC:


To send a message to your DS type something in the white textfield and click Send. You should now see the message string appear on your DS.
