This class provides empty abstract implementations for many methods that derived classes can override selectively; the default implementations represent a file that cannot be read, written or seeked. I'm programming under linux so "everything's a file", so I guess I just have to open serial for readingbut how to know if I'm reading the same integer or a new one?. Linux (at the operating system kernel level) supports four interfaces to a HID device - keyboard, mouse, joystick and a generic interface, known as the event interface. Now save the file and compile it using GCC at the terminal. Alternatively, you can add GRUB_TERMINAL="console serial" to have the grub menu on both serial and local console. In Linux all devices have a file in /dev directory, so the communication with these devices is very simple, just need to open necessary file, and make read and write operations upon them.
