If you are currently developing an embedded Linux or IoT application, tell me:
In Unix-like operating systems, . A serial port (such as /dev/ttyUSB0 or /dev/ttyS0 ) is represented by a character device file. When an application opens this device, the kernel returns a standard File Descriptor (fd) .
Despite the prevalence of Ethernet and wireless protocols, serial communication is not dead—far from it. It remains favored for several critical reasons:
