GetCommState returns wrong DCB fParity value RRS feed

  • Question

  • Windows 10 1909

    I open a serial comm device for overlapped I/O and set the DCB flow mask bit fParity=1 using SetCommState.  Later, when read back the DCB using GetCommState, everything in the DCB is correct except fParity, which always reads back 0.
