I am asking if it is possible to use a old arduino board (which has no arduino chip from where that died) as just a serial interface for my raspberry Pi

Does anyone know if this is possible and what application I can use to communicate with the serial port.

If there's no processor there's no serial port. So there's nothing to interface to.

Also the Pi already has a serial interface, can you tell us exactly what you want to achieve?

But the chip used on the board creates a serial port on the computer. What I am asking is can I use the usb serial chip to do it.

Ah OK, yes that should work. Just connect your Pi Tx and Rx signals to pins 1 and 0 on the Arduino headers. (Connect GNDs as well)
