Hi,
The new Dell inspiron laptops is using a new SMC chip called
FDC37N972. This chip is UART compatible for SIR speeds, but for some
reason, it's not working properly. I suspect that the Bios
initialization of the chip is not correct, so I've actually not
managed to make an IrDA connection on my own inspiron 4000 laptop yet.
