| Where are we at with IrDa and IRComm?  (how many times have I heard that
| question with still no clear idea of the answer? :!)

Benno Rice <benno@freebsd.org> and I are working on plugging
sio1 into Netgraph nodes for IrCOMM, IrTTY, IrLAN, Ir*.
(most IrDA controllers lie to the system as a serial controller
if there is no real irda driver, and they emit Ir just fine.
Try pointing your cellphone/PDA at your laptop's Ir port, and cat /dev/cuaa1)

IrLAN and IrTTY are our priority.  IrLAN provides ad-hoc cheap
wireless networking compared to IEEE802.11b.  IrTTY is what most
PDA's and cellphones use to connect to other systems.

<albertb@hga.com.tw> is writing a real driver for NatSem's IrDA controller
NatSem87338/97338 to take advantage of the hardware accel 
and ACPI/APM functions.  It should be no problem to plug the ng_ir* nodes
into device irda, just like we would do sio1. 

Since we can always fall back on sio* emulation of IrDA controllers,
we simply need to finish the ng_* nodes.  And voila, we have IrDA support.
USB serial IrDA devices would work, if n_hibma puts in the right support.
(I think even ugen would work.)  Firewire would work too, if 
we ever have an IrDA/IEEE1394 dongle.

Right now, we need :
* Someone who understands the NatSem87338/97338 controller driver well enough
  to tell us where we should plug the driver in.
* Someone who knows what is going ON with ACPICA, 
  what with the rapid changes and all
* Netgraph/net guru
* Someone to port the linux irda userland tools into the FreeBSD Ports
(In short, we appreciate any help we can get. :)

If you would like to help, email me with the area you want to help in.
I have all the documentation needed here.

The work is slower than snail's pace.  Benno is working on the 
FreeBSD/PPC port mostly.  I'm loaded with final exams, company work,
and libc/wchar*.h (Gah, can anyone make IrDA/ANSI C/NatSem documentation
more boring than it already is?)

This is only a quick answer to your question, Josef.  I hope
it answers your questions.
