You can use _software_ RS232 on any of the pins. The chip does not contain a UART, so there is no hardware RS232 ability. The software approach, is limited (the chip really musn't do anything else when sending or receiving, and the only way to do an 'automatic' receive, without having to poll the pin contnuously, is to use the external 'int' pin for the receive.
Whether this type of RS232 is adequate, will depend on what you need to do.

Best Wishes
