The Axon's pins are 5V logic and the serial COM port on a PC is RS232 levels (google this).
At a minimum you need a MAX232 chip to translate to voltage level between the Axon and PC.
Look at the SoR tutorials above for more info.

If all you want to do is use the UART to communicate with the Axon through your PC, you should just use the USB connector on it. All you need to is install the driver from SILabs (https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx) so that your PC's terminal program or whatever will recognize the Axon.

Edit: just read this part of the Axon2 setup tutorial: http://www.societyofrobots.com/axon2/axon2_setup2.shtml. It should be pretty straightforward.

The only way to top an upright screen, keyboard, and mouse is to eliminate the need for humans to touch a PC at all. Oh, hello there Mr. Robot... what would I like you to do, you ask?
