We are using a USB-to-Serial converter. Windows assigns a COM port number to the serial device. For testing purposes, we need to control the COM port number assigned by Windows. For example, we would like to tell Windows to assign COM 255 to a device rather than have Windows decide what the number is. Is there any way to do this?

I do not have to do this programmatically, so Nacereddine is right. My Computer -> Manage -> Device Manager -> Ports -> Communications Port -> Port Settings -> Advanced -> COM Port Number
