- There isn't one for that board, sorry. The 35/indigo reset resets
- the parallel 'bus' as well as the chip. There is an ioctl (for at
- least some revs, that does a board reset), but the driver does the
- same thing anyway when the port is closed, if it thinks the board is
- hung. Still, you could try IKIORESET, the 3rd arg to ioctl is ignored
- for this. It is definied in sys/ik_ioctl.h. I have no idea if it
- works or not; it definitely isn't documented on the ik man page.
