This is normal this is the driver telling you the baud rate has been
changed to 9600.

How are you testing if anything is being transmitted?

I tried to reproduce this here and everything was transmitted properly.
How are you testing this? I'd recommend connecting a null modem cable
to COM3 then starting a terminal emulator on the PC the null modem
cable is connected to set the terminal emulator to use 9600,8,n,1.
Finally from the command line run the following command.
echo 1234567890987654321 > /dev/ttyTS0
You should see the string 1234567890987654321 appear immediatly in your
terminal emulator.
