Can you tell me how to specify the serial port output by the terminal on the Linux ARM (just give me a prompt)-General Linux technology-Linux technology and application information? The following is a detailed description. Half of the development boards running Linux on ARM have a dedicated serial port used to output terminal information. This serial port is generally configured with 115200 N 1. I would like to ask you to specify which technology is used for such a serial port?
I just want to give you a tip. Maybe you can point your point in a concise way, so that I can find the information on my own. This is also the correct learning method, isn't it?
