1. Connect Tx, Rx and GND between serial port on PC or USB or serial convertor and ur microcontroller board RS232.
2. Set up an interrupt routine for RS232 communication in MCU, so that whenever u type in any letter the transmit receive register will receive the byte, save the byte in RAM and reset the interrupt flag bit.
3. Connect 16x2 lcd
