Linux serial port I/O mode As we all know, in Linux, all devices exist in the form of files, and the serial port is the same. Generally, I/O operations are implemented in two ways: blocking and non-blocking. The concept of "timeout" is actually a processing method in blocking, and it is actually a blocking I/O mode. I
