Posez votre questionI have found that I can do fopen("COM1:", "r+"); to open the comport in windows. You have to make sure the comport isn't already open or you will get a permission denied. (J_G => ben ouai, c'était évident ) I am still playing around with this but you have to somehow flush what you send to the comport if you are trying to communicate realtime with a device.
