To my understanding SIR is one mode of the lowest IrDA level (IrPHY). It was defined by HP long before the rest of the IrDA stack (IrLAP, IrLMP, IrCOMM, ...) In such a reduced form it is implemented in HP Palmtop 200LX. If I am right, it is nothing else than serial communication with 9600bps to 115.2kbps using infrared transmission. That means not a single protocol byte is added to the data stream as it is done when using the higher layer IrCOMM. Please correct me if I am wrong. Now to my problem: When I plug the Tekram IR-dongle to COM1, one might suspect that I can connect to HP200LX by using directly /dev/ttyS0. This is actually the case but only for 9600bps, the default speed of Tekram dongle. Why? Because to change the dongle speed a special procedure has to be done on the serial control lines as one can see in kernel file tekram.c. So I would prefer to use IrDA stack together with Tekram driver, with a possibility to directly access IrPHY layer. I don't know if this is possible in Linux IrDA implementation? The needed package specifically for this purpose (communication with HP200LX) that you mentioned is available. It is LXtools which was primarily written for RS232 (wire !) connection. I just search for a proper Linux /dev/? to do the same with IR.
