The "/dev/screen/pavi FIRST_MOUSE" string would be used to open the
first mouse on the HP-HIL loop as an X extension input device.  However
that device is not available as an extension device because the X server
is already using it as a pointer device.  Instead, you can open the
window name itself as an input device.  That will use the X server
pointer device for locator input and choice input.  The X server
keyboard device for can be used by the sox11 driver for another choice
device.  To use the sox11 driver try the following.

	if ((display = gopen("/dev/screen/pavi", OUTDEV, "hp98550", INIT)) == -1)
		exit(1);
	if ((input = gopen("/dev/screen/pavi", INDEV, "sox11", INIT)) == -1)
		gclose(display), exit(1);

Now the mouse position will be locator ordinal 1 on "input".  The mouse
buttons are reported as button numbers on choice ordinal 1 and as a button
state bitmask on choice ordinal 2.  The keyboard will be choice ordinal 3.

You could just open the window once with output and input as below, but
the "hp98550" driver inputs from only the mouse and doesn't do input
from the keyboard.

	if ((window = gopen("/dev/screen/pavi", OUTINDEV, "hp98550", INIT)) == -1)
		exit(1);
