your problem description is very unprecise.
Do you mean you are not able to pipe a dictionary or another's process output to oclHashcat ? That should indeed work without any problem.
... or do you mean that you can't control oclHashcat itself (status, quit, pause, resume, bypass etc). This needs a little trick...
but that also slightly depends on the operating system you are working with. Therefore, you should also have specified on which (operating) system it doesn't work.
And yes, oclHashcat for sure uses stdin (for case 1: piping output to oclHashcat and case2: control the process if stdin is not in use, both at the same time is of course not possible, i.e. for case 1 you need to "kill" the process because stdin is in use because of the pipe).
