title: Using DMA to access High Speed Serial Port
body: <p>I use serialport component in c# and it works well! But the question is how can it be faster to handle high speed (e.g. 2 Mbps) data transfers.</p>
  
  <p>As I have researched about this, I have found that memory can be accessed directly (using DMA like <a href="http://www.eventhelix.com/realtimemantra/patterncatalog/high_speed_serial_port.htm" rel="nofollow">this link</a> ).
  Can anybody tell me how can I define and use it in my application?</p>
