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.

--- Vivi Li 2009-08-05 02:56:56

OK, close it.
