Whats best for 2-way communication over Serial

I want to have a PIC talking to a PC over a serial port sending and receiving info.
Can I use SPI for this or do I need UART or something else?

Hello
For this you will need a PICmicro with a UART and you will also need some extra components to do the voltage level shifting. We use a MAX232 chip on our RS232 E-Block. However if you google some PIC serial projects you will find versions that get away with using resistors to do the 12V to 5V conversion.

I am new to flowcode (have V3)
I need the same function (sending and receiving characters),
Is there a sample for this routine for download?
Best regards
