Serial interface
All Oscar cameras are equipped with the SIO (serial input/output) feature as
described in IIDC V1.31. This means that the Oscar's serial interface which is
used for firmware upgrades can also be used as a general RS232 interface.
Data written to a specific address in the IEEE 1394 address range will be sent
through the serial interface. Incoming serial interface data is put into a cam-
era buffer and can be polled from here via simple read commands. Controlling
registers enable the settings of baud rates and the check of buffer sizes and
serial interface errors.
Base address for the function is: F0F02100h.
