When J1 is open the terminal operate as a normal ascii display terminal, when J1 is closed the terminal displays the input serial data in hexadecimal format. This mode is useful for viewing raw data from the serial port output. IC U2 a PIC16F84 micro controller is used to control the operation of the terminal. Input signal is applied to connector K1.
