I use the kernel checked out doday, toolchain RC9, irdaping, ircp works fine.

I changed the irtty from COM4 to COM2 by setting the notebook's BIOS.


Would you test it under windows again?


--- Graf Yang                                                2009-08-03 03:28:34

irdaping a windows host will not get any response.

You'd use it to ping a linux host.

It's not a bug.

OK, close it.
