Any Way To Interrupt 6533 Patterned Output?

[leevonk]

I programmed my PCI 6533 card via c++ to output patterns but is there a way to interrupt it and give it a new pattern before it's done with the current pattern? I tried setting the stop trigger to hardware but got an error when I did that (I think it was: this mode is not valid for the device" or something), a small bit of c cample code would be great, thanks for any help.

I found the function:

iStatus = DIG_Block_Clear (deviceNumber, group);

which seems to work, (it interrupts the buffer output) thank you!
