<div dir="ltr">I'm running eprime pro and trying to use task events to trigger an external device.<div><br></div><div>When the stimulus comes on the screen, I need eprime to send the string "RUN" to the serial port.</div><div><br></div><div>In task events, I do the following:</div><div>-Add an event</div><div>-Select the serial device (COM3)</div><div>-Action: WriteString</div><div><br></div><div>...but then how to I define what the string is? (i.e. "RUN")</div><div><br></div><div><br></div><div>(In a terminal window, i can type "echo RUN > COM3" and that triggers the device...I'm just trying to figure out how eprime to do that.)</div><div><br></div><div>Thanks! </div></div>
