I want use the serial port on the pins on the Linux side of the ODYSSEY-X86J4105. I assumed the port to use was ttyS0 because there is no ttyS4 see images below (I am a new user so I can only add one image so I had to work around that):

I opened two terminals, one on a windows pc and on the ODYSSEY-X86J4105.
ODYSSEY:

Windows:

I sent text files over both terminals. The windows pc has a file with U and a File with Q
ODYSSEY received for U:

ODYSSEY received for Q

ODYSSEY just sent the U file and windows pc received:

The oscilloscope reading also looks strange form the ODYSSEY side but relatively normal form the Windows pc side. The ODYSSEY “arduino” serial is fine and does not cause the same problem sending to the windows pc. I also tried c and python code to with a similar results. My usb serial converter that I plugged into the ODYSSEY also works.
I would like to know if anyone has experienced this before and how I could possibly solve the problem and if I am missing something?
