SetComState() is what you need to use.  Did you call GetComState() before
calling SetComState()?  What is the actual problem you're having?  Just
saying "it doesn't work" says nothing at all about the actual symptoms
you're experiencing.  Please be more specific.

If you read the documentation for DCB, you might notice the following
members, amongst others:

    DWORD fOutxCtsFlow:1;      // CTS output flow control
    DWORD fOutxDsrFlow:1;      // DSR output flow control
    DWORD fDtrControl:2;       // DTR flow control type
    DWORD fOutX: 1;            // XON/XOFF out flow control
    DWORD fInX: 1;             // XON/XOFF in flow control
    DWORD fRtsControl:2;       // RTS flow control
