You either have a dead controller chip, or a blank one that needs a firmware or your tring to talk to the board at the wrong baud rate
Try a few baud rates, will normally be either 250000 or 115200. Nb some machines will just will not talk at 250000...
failing that its time try to work out how to compile the code and upload new firmware... (im presuming the chip is ok, and has a boot rom but otherwise is empty....)
get the arduno IDE and the firmware you want to run, add in the sanguino extentions
Some help here [www.geeetech.com]
When you can compile the code ok its time to upload to the chip (make sure you have the auto reset jumper in place)
