UART / Universal Asynchronous Receiver/Transmitter for Not Yet Techies

"Computer Careers: Using This Microchip to Control a PC's Interaction With Serial Devices"

by Richard Stooker, President Info Ring Press and author of Secrets of Changing to a Computer Career

UART / Universal Asynchronous Receiver/Transmitter is a microchip with programming controlling a computer's interface to attached serial devices. UART / Universal Asynchronous Receiver/Transmitter chips are the basis of many serial ports. They take parallel information off data buses and turn it into serial information for modems or other devices requiring one bit by one bit data transmission. They also take that serial information and turn it into parallel data to into a data bus for computer usage.

A UART / Universal Asynchronous Receiver/Transmitter chip provides computers with the RS-232C Data Terminal Equipment (DTE)interface. It also provides error checking and buffering so that the data streams remain coordinated.

The original UART / Universal Asynchronous Receiver/Transmitter was the 8250. Now you'll find the 16550A or higher

UART / Universal Asynchronous Receiver/Transmitter chips are used on COM ports.
