baud 115200 means 115200 bits per second only if each baud = 1 bit. If each baud is 5 bits, then having baud 115200 means a bit rate of 115200 * 5 bits per seconds.

I am trying to find out what bitrate is supported by NX UART
It seems that folks with TX2 got it more like 8Mbit/S, right? So will it be the highest possible bitrate for the NX devkit? Or even 1Mbit/S is problematic?
