Hi, I have a PIC18F4520 which has only 1 usart.
I currently have a ID-12 RFID Reader connected to the RX pin which i use to read the RFID and perform some actions. But now I want to be able to write to the PIC via RS232, and strike a problem that I cannot use both RS232 and the RFID reader.

Does anyone know how I can resolve this issue.

Using a different PIC is not an option.
