We have our BrightSign device that is connected to a display and running our custom node application. This node application is listening for messages from our website. Our users will have a dashboard for viewing all of their devices. From this page, they can send a message to power the display ON or OFF. Our Node application will receive the message from our website. We would like to use this node application to send serial commands to turn the display on and off when these messages are received. The only piece of all this I need help with is the sending of the serial commands from Node.
Thanks
