Control two computers simultaneously

Hi, I was writing to ask if it is possible to have one experimenter computer that sends instructions to two participant computers simultaneously? My experiment will involve having two participants working at the same time, seeing the same stimuli simultaneously. The timing is key. Is it possible to do it with inquisit? Thanks!

You may be able to set something like this up by sending signals from the experimenter computer via the parallel port to the two participant computers. You would, of course, need a splitter cable to get the signal from the one experimenter machine to the two participant machines. Will this be easy or straightforward to set up (if at all possible)? No.
