Hi expert,


I want to confirm these information about UART:

1. @IMX6SL platform, UART parity only have ODD/EVEN mode, but not contain MARK and SPACE, is it right? Further more, is there any upgrade for this to support MARK & SPACE?


2. about the flow control, the spec shows that this platform only support RTS/CTS HW flow control.

what is it about DTR/DSR?


3. how to use SW flow control (XON/XOFF)?



Thank You!
