Interfacing With YEI 3-Space Sensor


I have an Arduino Mega ADK, and I am trying to interface with the YEI 3-Space Sensor. It uses a USB cable to plug into the Arduino, and serial commands are sent over. For example, sending over something like :1 in CuteCom yields the expected result of current angle. Is there a way that I can send serial commands over USB? This also involves things like flipping to Big and Little Endian. Also. I am kind of new to this, so does anybody have a tutorial on how to import the right things to do this.

This is a link to the support page:

It has some serial communication examples in Python and C++, if that helps anybody.

Thanks in advance!
