One of the most commonly used and easy to use protocol in serial communication is USART. It is the abbreviation for Universal Synchronous Asynchronous Receiver Transmitter. It is the commonly used asynchronous communication protocol and available in vast variety of devices. For example, GSM modems, GPS modems, sensors etc. Advantage of asynchronous communication is it doesn’t need a clock for syncing data between two devices. RS-232 The computer has serial port which uses RS-232 interface standard and it is one of most reliable communication standard using UART protocol.

RS-232 voltage levels are different from TTL levels and a voltage level converter is need when interfacing with PIC Microcontroller board. Interfacing PIC Microcontroller have inbuilt UART module which is very easy to interface. There are two pins for UART module, TX, transmitter and RX, receiver. When interfacing to other devices, Tx will be connected to Rx of the other device and Rx will connect to Tx.
