			has the following elements
	    gpt_Keys -
		    GPTB_DOWNKEYS set if button down transitions
		    trigger a report, and GPTB_UPKEYS set if button up
		    transitions trigger a report
	    gpt_Timeout	-
		    a time which, if exceeded, triggers a report;
		    measured in vertical blank units (60/sec)
	    gpt_XDelta	-
		    a distance in x which, if exceeded, triggers a
		    report
	    gpt_YDelta	-
		    a distance in x which, if exceeded, triggers a
		    report

input.device/IND_SETMTYPE                           input.device/IND_SETMTYPE

   NAME
	IND_SETMTYPE -- Set the current mouse port controller type

   FUNCTION
	This command sets the type of device at the mouse port, so
	the signals at the port may be properly interpreted.

   IO REQUEST
	io_Message	mn_ReplyPort set if quick I/O is not possible
	io_Device	preset by the call to OpenDevice
	io_Unit		preset by the call to OpenDevice
	io_Command	IND_SETMTYPE
	io_Flags	IOB_QUICK set if quick I/O is possible
	io_Length	1
	io_Data		the address of the byte variable describing
			the controller type, as per the equates in
			the gameport include file

input.device/IND_SETPERIOD                         input.device/IND_SETPERIOD

   NAME
	IND_SETPERIOD -- Set the key repeat period

   FUNCTION
	This command sets the period at which a repeating key repeats.

	This command always executes immediately.

   IO REQUEST - a timerequest
	tr_node.io_Message	mn_ReplyPort set if quick I/O is not possible
	tr_node.io_Device	preset by the call to OpenDevice
	tr_node.io_Unit		preset by the call to OpenDevice

input.device/IND_SETTHRESH                         input.device/IND_SETTHRESH

   NAME
	IND_SETTHRESH -- Set the key repeat threshold

   FUNCTION
	This command sets the time that a key must be held down before
	it can repeat.  The repeatability of a key may be restricted
	(as, for example, are the shift keys).

	This command always executes immediately.

   IO REQUEST - a timerequest
	tr_node.io_Message	mn_ReplyPort set if quick I/O is not possible
	tr_node.io_Device	preset by the call to OpenDevice

input.device/IND_WRITEEVENT                       input.device/IND_WRITEEVENT

   NAME
	IND_WRITEEVENT -- Propagate an input event to all handlers

   FUNCTION

   IO REQUEST
	io_Message	mn_ReplyPort set if quick I/O is not possible
	io_Device	preset by the call to OpenDevice
	io_Unit		preset by the call to OpenDevice
	io_Command	IND_WRITEEVENT
	io_Flags	IOB_QUICK set if quick I/O is possible
	io_Length	should be sizeof(struct InputEvent)
	io_Data		a pointer to the struct InputEvent:
	    ie_NextEvent
			will be ignored.
	    ie_Class
	    ie_SubClass
	    ie_Code 
	    ie_Qualifier 
	    ie_X, ie_Y
			as desired
	    ie_TimeStamp 
			will be set by this call (V36)

   NOTES
	The contents of the input event are destroyed.

	This function was documented in V34 and earlier to allow
	chaining of events via ie_NextEvent.  The implementation
	never allowed that.  The documentation now reflects this.

	ie_TimeStamp is set only in V36 and later.  Software written
	to run on earlier versions should set this field to the
	current time.

input.device/PeekQualifier                         input.device/PeekQualifier

   NAME
	PeekQualifier -- get the input device's current qualifiers (V36)

   SYNOPSIS
	qualifier = PeekQualifier()
	d0

	UWORD PeekQualifier( VOID );

   FUNCTION
	This function takes a snapshot of what the input device thinks
	the current qualifiers are.

   RESULTS
	qualifier - a word with the following bits set according to
	    what the input device knows their state to be:
		IEQUALIFIER_LSHIFT, IEQUALIFIER_RSHIFT,
		IEQUALIFIER_CAPSLOCK, IEQUALIFIER_CONTROL, 
		IEQUALIFIER_LALT, IEQUALIFIER_RALT,
		IEQUALIFIER_LCOMMAND, IEQUALIFIER_RCOMMAND,
		IEQUALIFIER_LEFTBUTTON, IEQUALIFIER_RBUTTON,
		IEQUALIFIER_MIDBUTTON

   NOTE
	This function is new for V36.
