I'm guessing that most people just use 'Driven' mode.
But I'm thinking(not usually correct) that 'Open' mode with a pull-up resistor is best practice, but limits the UART(Serin/out) to only non-inverted(True) mode.
Any comments?
Thanks in advance!
Using (software)UART Driven vs. Open ? Whats best practice?

Hserout (USART) is as you surmised OT with a pull up. I have experienced some lock ups when pull up is left out or too low impedance. I am pretty sure USART is only True
