Output signal from usb port

Question

My understanding of "signal" is that it is analog, but it is possible that it also refers to digital data. A serial connection is digital data only. So perhaps you need to send digital data that creates an analog signal. If so then you will need to use the specifications for the device to know what data to send. You need to read the articles in this web site about serial communication. Then ask specific questions. It is less likely that you will get help when you ask general questions (such as you have here) about how to do something. Most programmers that don't have many years of programming and do not have experience working with hardware do not know how to do serial communication. Serial communication is not easy. I hope someone can help you but you probably need to spend more time learning about serial communication.
