I have been trying to write code to connect a HiTechnic prototype board to my lego brick. Although I am using MSRDS studio, that isn't the issue; reading and writing to the serial port that the device is connected to works fine.
Where I am lacking is that I don't understand the data is that is being sent and received. It goes out and comes back in the form of a byte array. For example:       
Is this byte array converted from hex? What is this response telling me?
Obviously I am a total newbie at this, I can program but I don't really understand electronics and I am trying to make that connection between what I have read about how an I2C controller works and what is happening when I send and receive data over a serial port.
