title: C#/.NET wrapper for serial port WIN32 Comm API
body: <p>I am looking for a way to have as much control as it is possible over serial port in my c# application. The problem is that I need to communicate with a device that has no documentation except for an old c++ program written to control it. I've tried to use SerialPort class to communicate with the device but its behaviour is quite odd (I have to repeat some of the commands, some other commands dont work at all).
  I would like to copy that unmanaged program's behaviour, however it seems to be impossible with serialport class, as it does not provide access to low-level functions and structures like DCB for example.</p>
  
  <p>Are there any low-level wrappers for serial communication available for .net? Maybe i could use reflection to manipulate serialport innacessible members at runtime?</p>
