Subject: [PATCH] WinSerialPort: Set DTR behavior explicitly

Some serial terminal applications apparently change the default DTR behavior ("turn off and keep off"); this causes BOSSA to fail, e.g. on the Arduino Due, until the parameter is reset or the serial device is disconnected and reconnected. Make BOSSA set this parameter explicitly.
