It seems from the docs that in the default device tree, the uart pins are set to bidirectional. In serial communication TX should not be able to receive, and RX should not be able to send. I'm afraid that If I keep it default i.e. bidirectional, it might work weird or worst might fry the ports.
Well, thanks for the info. I'll try it. I'm a newbie, so still learning how to edit the device tree.
