It was also an early hardware system for the Internet.Ī UART is usually an individual (or part of an) integrated circuit (IC) used for serial communications over a computer or peripheral device serial port. It was one of the earliest computer communication devices, used to attach teletypewriters for an operator console. Two common signal levels are RS-232, a 12- volt system, and RS-485, a 5-volt system. The electric signaling levels are handled by a driver circuit external to the UART. It sends data bits one by one, from the least significant to the most significant, framed by start and stop bits so that precise timing is handled by the communication channel. A universal asynchronous receiver-transmitter ( UART / ˈ juː ɑːr t/) is a computer hardware device for asynchronous serial communication in which the data format and transmission speeds are configurable.
