Hello,
I already know the machine.
The machine that i will use is the Medtronic Keypoint classic (neurophysiological stimulation). This machine has an input in form of male COM port. I need only an electric input, like a circuit closing or switch, coming from the software DirectRT, when a picture is showed in order to elicitate an electric stimulation output from Keypoint. Do you understand? if any exlplanation is needed i would be glad to answer questions.

My question is, can I do this with DirectRT and a laptop?

Thank you very very much
