If findchip cannot find your chip, then there is no way the SMC driver is
going to find it!

irda-utils-0.9.9/irattach/README should explain it!

No there is a very big difference on /dev/ircomm0 and /dev/ttyS?

+--------------+
|    IrCOMM    |  /dev/ircomm0
+--------------+
|    IrTTP     |
+--------------+
|    IrLMP     |
+--------------+
|    IrLAP     |
+--------------+
|     | IrTTY  |  /dev/ttyS? (when using IrTTY)
| SMC +--------+
|     | Serial |
+-----+--------+

So you can see that /dev/ircomm0 binds you application to the top of the
IrDA stack, and if you use /dev/ttyS? for pilox-xfer then you will not 
use the IrDA stack at all. You use /dev/ttyS? to irattach, to bind the
bottom of the IrDA stack to a low level serial driver! So you can run IrDA
over a serial port compatible IrDA port, or a serial port which has a
IrDA dongle attached to it. 

You don't want to use "irattach /dev/ircomm0" since that would make you run
IrDA over IrCOMM (replace serial with IrCOMM in the figure above). I've
tried it and it works, but I haven't found any good use for it yet ;-)

Yes!

The Palm cannot speak in FIR mode, so there is no reason for you to try out
the SMC driver. Use "irattach /dev/ttyS? -s" instead.
