When you try to connect an external device to Oudie with a serial cable and it doesn't work out of the box the most likely culprit is that the devices are communicating at different speeds and/or COM ports.

The best way to make sure Oudie sees the other device is to do the following:

1. Go to Menu > Settings > Hardware > Terminal > Port Settings.

2. Change the COM port to COM 4 (Serial port).

3. Change the baude rate from 4800 to 115000 one at a time. Press OK each time you cahnge the baude rate.

4. If the text in the Terminal becomes human readable, you are done. If it's not, keep increasing the baude rate.
