image_download_8250()

unsigned int image_download_8250 (port, span, address)

Downloads an image from the specified serial port (port) to the specified address (address) using a custom protocol. On the host side, this protocol is implemented via the utility sendnto (you may need a NULL-modem cable — the protocol uses only TX, RX, and GND). The span parameter indicates the offset from one port to the next port on the serial device.
