NAME
	KBD_ADDRESETHANDLER -- Add a keyboard reset handler.

   FUNCTION
	Add a function to the list of functions called to clean up
	before a hard reset generated at the keyboard.  The reset
	handler is called as:
	    ResetHandler(handlerData)
	                 a1

   IO REQUEST
	io_Message	mn_ReplyPort set
	io_Device	preset by OpenDevice
	io_Unit		preset by OpenDevice
	io_Command	KBD_ADDRESETHANDLER
	io_Data		a pointer to an interrupt structure.
	    is_Data 	the handlerData pointer described above
	    is_Code	the Handler function address

   NOTES
	Few of the Amiga keyboard models generate the communication codes
	used to implement this reset processing.  Specifically, only the
	Euro a1000 (rare), and the B2000 keyboard generate them.

	The interrupt structure is kept by the keyboard device until a
	RemResetHandler command is satisfied for it, but the
	KBD_ADDRESETHANDLER command itself is replied immediately.
