Is the IrDA UART setting the same for the TX and RX signals?

I'm trying to use IrDA UART in Nios II to send and receive signals to an FTDI 232. I am using the UART setting: 9600bps, none parity, Data Bit 8, stop bit 1. I can perfectly read the information ...

The input and output signals of the IrDA UART core are different, input signal follows the UART protocol but output signal follows another protocol, I believe the difference is necessary to transmit the information through a photoemitter, allowing it to be received by a phototransistor.

For two-way UART communication, the most correct is to use RS232 UART core. My problem has been solved.

Thank you for your interest.
