I'v heard several ideas about the usage and yes - this usb-serial
emulated connection can be used for whatever communications between
dongle and Linux host. Of course it depends on FPGA firmware. I am not
aware about the possibilites to custom-program the FPGA (for one
dongle). This sould be asked again from Artec Group guys.
