TWR-PXR40 OSJTAG serial port parity options

I have the TWR-PXR40 board and I am working on serial port code.


When connecting using the onboard OSJTAG which creates a CDC USB to serial port, I could not get odd parity to work.


Is this mode unsupported by the OSJTAG CDC port?


I connected a separate USB to 3.3V TTL serial port to the TWR-PXR40 by removing jumpers and was able to get the communications to work with odd parity. Required connection for our device is 115,200 8 bit Odd parity 1 stop bit no flow control:




Thanks, Ian
