The system will do it for you (I believe), but you /do/ have to make sure you not only specify that you want that kind of flow control in the DCB when you open the port, but also what character is going to be used (DCB members fOutX, fInX, XonLim, XoffLim, XonChar and XoffChar. You may also want to look at the fTXContinueOnXoff member, although it should not affect whether the system handles it for you or not). -- Jason Teagle [EMAIL PROTECTED]
