Mk3 raspberry pi port

I have a question regarding the communication on the Mk3 raspberry pi port on Rambo PCB used on the MK3.  

According to PCB's schematic there is a Tx and Rx signal.  What is the format of these signals (i.e baud, character set, etc.). 

Thank you

Mark

There is a reasonable chance it is the same when connecting via USB.  And for that, looking at the terminal output in octoprint I got

port='/dev/ttyACM0', baudrate=115200, bytesize=8, parity='N', stopbits=1, timeout=10.0, xonxoff=False, rtscts=False, dsrdtr=False

serial port /dev/ttyAMA0, digital pins (0,1,16,17), RX0/TX0-UART1, default baudrate 115200, max. 250000.

More detailed info can be found by exploring the firmware source code, which you can find here: https://github.com/prusa3d/Prusa-Firmware
