    "1. Is is possible to use an IRDA port on a PC in the same way as a RS232 port?"

    Your PC will have "virtual" LPT and COM ports which use the IrDA link.

    "2. Can an IRDA tx/rx device be put in place of a RS232 driver (MAX232)?"

    What do you mean by "IRDA tx/rx device?" are you thinking of those Microchip devices which embed the protocol in hardware? If so, then yes - I think that's the idea.

    But if you're thinking of just replacing your MAX232 with an IR emitter & detector - well, you would get something, but it wouldn't be IrDA!
