Well, if you are still using this code:

Then, according to your own comments, you are overwriting
my_DCB.Parity, and the other my_DCB settings with the results from
BuildCommDCB().
Don't know why you would want to set the values twice in the first
place. Choose one method (manual or BuildCommDCB() ) and use only
that.
