Serial interface
All GUPPY cameras are equipped with the SIO (serial input/output) feature
as described in IIDC V1.31. This means that the GUPPYs 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 in the cam-
era buffer and can be polled from here via simple read commands . Control-
ling registers enable the settings of baud rates and the check of buffer sizes
and serial interface errors.
Base address for the function is: F0F02100h.
