It was introduced first in 1980 and later standardized as IEEE 802.3 in 1985. When talking about Ethernet standards, those are tightly connected with the OSI physical layer. Ethernet provides service up to and including the data link layer.

The standard is used mainly in serial ports of computers, which are also called “COM” ports in everyday language. Nowadays is the RS-232 largely replaced by USB interface, but due to its simplicity it is still used very successfully in hobby applications, especially if there are USB – … text/html 2026-02-19T09:30:59+00:00 Anonymous (anonymous@undisclosed.example.com) https://home.roboticlab.eu/en/examples/communication/uart?rev=1771493459&do=diff Serial interface UART Required knowledge: [HW] Kontrollermoodul, [HW] Kombomoodul, [AVR] USART, [LIB] Jadaliides, [LIB] Graafiline LCD Theory UART stands for “universal asynchronous receiver/transmitter”. USART is almost the same, but with the difference that data is transferred together with a clock signal. UART can also be called a serial interface. A serial interface is a data transfer mechanism where each bit is transmitted one by one.
