	Just yesterday I got in a Hitachi HDG-1111C digitiser tablet
for our 280 (IRIX 3.3.1). Useing the very sparse documentation supplied,
I installed it on port ttyd1 and started the daemon tabletd.
	One of the users then attempted to use the tablet from within
a program but found that the 4 button mouse would not produce an event 
recognized by the event queue or a value from getvauator(). I know that
the tablet is working as I can stop tabletd and read the output from the
tablet with no problems. 
	Below is a code fragment of the program trying to detect an event
from the digitiser.

#include "gl.h"
#include "device.h"
#include "fmclient.h"
.
{
.
qdevice(BPAD0);
qdevice(BPAD1);
qdevice(BPAD2);
qdevice(BPAD3);
.
while(1){ dev=qread(&value);
	.
	else if (dev==BPAD1)
	{	xpad=getevaluator(BPADX);
		ypad=getevaluator(BPADY);
	}
.
.
	All sugestions,help, etc greatfully accepted.
