A universal synchronous and asynchronousreceiver-transmitter (USART, programmable communications interface or PCI) is a type of a serial interface device
overall transmission speed in characters per second. Asynchronous start-stop is the lower data-linklayer used to connect computers to modems for many dial-up
networks. For example, IP may be tunneled across an Asynchronous Transfer Mode (ATM) network. Protocol layering forms the basis of protocol design. It allows
