Serial with Mark/Space Parity

Postby iwalker » Mon Jan 02, 2017 9:12 am

Hi There

I need to talk to a device that requires 9 bit serial where the 9th bit has to be set high to let the device know it is being addressed.
On Arduino I managed this by manipulating the relevant serial control registers.
Is this possible with the ESP32 and where can I find details on the serial control registers for this chip ?

Try using 2 stop bits for mark parity.
