 **Note:** See documentation for more commands and details about the LEGO NXT Communication Protocol {{:alvarop:appendix_2-lego_mindstorms_nxt_direct_commands.pdf| NXT Direct Commands}}
-There are several methods you can you go about sending direct commands. There are programs that allow you to send data to certain COM ports, but most of these are only good for testing and not writing programs that utilize the COM ports. This tutorial will demonstrate the use of the C++ Serial Port class in Windows that can be used to write programs that send data to COM ports, thus allowing the user to send direct commands to the NXT Brick with a C++ program.

   - Under the "COM Ports" menu are the current COM Ports assigned to different devices. Find the Outgoing Port for the NXT and take note of it. It will be used later in the tutorial.
   - Open the sample code and read through the comments to get a general idea of what the program does
+  - Change the values for the motor variables MotorL and MotorR to your NXT Bot's corresponding ports
   - Build and run the the solution, when prompted, enter the COM port that the NXT Brick is currently utilizing
