// Clean up close(fd); return EXIT_SUCCESS; Compile with: serial port c example

int fd = serial_open(device, baud); if (fd < 0) return EXIT_FAILURE; printf("Serial port %s opened at 115200 baud\n", device);

// Wait for response char response[256]; serial_read(fd, response, sizeof(response)); // Clean up close(fd)
