Evgeni, you might want to take a look at the Maxim MAX3100 UART which,
in addition to UART fuctions, supports the IrDA spec at 115.2K. It uses
an SPI/Microwire compatible interface and the TxD and RTS outputs will
sink 25ma for use with opto-isolators. It comes in a 14 pin DIP or a 16
pin QSOP package. I have a couple of 115.K IrDA modules from HP that I
want to interface to the MAX3100 and the 16F84.

You were right - the extra 2 pins are for future use, so now I'm happy.

possible to implement an IrDA device with PIC. I have all the standards

PICs to estimate that task.
