For the PC serial port RX line the minimum voltage levels are defined as ±3V i.e. to receive a logic zero the voltage must be greater than 3V and to receive a logic one the voltage must be smaller than -3V.

Design appropriate circuitry to connect the PC Serial Port RX line to the PIC16F18877 USART TX line. Explain how component values would be chosen, how you would configure the pin for the TX line, and how you would verify that the PIC16F877 will operate as required, yet not be damaged.
