I have a AT89C51RD2 microcontroller but accidentally disconnected a VCC or GND to pin connection and now RS232 communication is not possible. I do not remember what the connection was exactly but it was VCC or GND to some pin. Does anyone know what the connection could be? I am using a plain RS232 cable.
My final goal is to load a hex file using FLIP to the microcontroller.
I am not familiar with hardware at all so please forgive me if my description is severely lacking.
