Do noy ty rs232 lines form a computer com-port of usb to serial port directly to the controller. It could fry the serial bus on the controller.

Make sure your interface talks TTL 5volts and 0Volts or 3.3 and 0Volts.

Standard RS232 uses positive an negative voltage.
These voltages could be up to +13Volts and -13Volts !

Using a FTDI-cip can work with both the 3.12 version, and also the newer software as explained in the buggies forum.
For 3.12 you only need to invert Rx and TXD signals.
