I assume you did something along the lines

/sbin/modprobe ni_pcidio

checked dmesg 

"comedi: version 0.7.69 - David Schleef etc
Available NI device IDs 0x0160"

comedi_config /dev/comedi1 ni_pcidio

checked dmesg

comedi1: nidio:MITE:"????????" mappped to "????????" DAQ: etc
pci-dio-96

then run dio from the demo program  directory with

./dio -f /dev/comedi1

"note the -f "

If you edit the program

mask=0x00FFFFFF;
for(;;){
                data = 0x00ffffff;
                comedi_dio_bitfield(device,subdevice,mask,&data);
                usleep(10);
                data = 0;
                comedi_dio_bitfield(device,subdevice,mask,&data);
                usleep(10);
                }

you should get a square wave. Forever.
