IrDA on PowerBooks

IrDA on PowerBooks

[Topi Kanerva]

hello. I'm addressing you of this problem of mine because someone out
there might already know the answer so I don't have to dig through all
those kernel sources. I'm trying to get my Ericsson R380s phone to
talk to my Pismo PowerBook. For some reason it plainly does not
work. I cannot be configuring wrong all that IrDA protocol stuff, so
there must be something fundamentally wrong. I suppose IrCOMM only
supports SIRs emulating the 16550A serial chip, and from the kernel
log one can notice that the PowerBook seems to utilize Z8530 chips
which I suppose is a different thing altogether.  Can I just snatch
some Z8530 code from other driver sources, e.g. the stuff for the old
TurboChannel DECstations which used this chip for their keyboard
etc. i/o?  I'm just running quite short on time, since this is really
needed for the CEO of our company, since I persuaded him to get a
PowerBook to run Linux on... sheesh.

Now, anyone who has succesfully got any IrDA devices to work with the
PowerBook IrDA port? any suggestions?

don't know anything about the ericson, but as long as you followed
the IRDA-HOWTO, it should work right out of the box.
get the irda-utils src, or use debian's package.
and there is a gsmlib-rpm at linuxppc, which manage your sms (no GUI).
	I did't try that one, 'cause I use irda only for the palm.

# irattach /dev/ttyS1
# irmanager -d 1
and after that it's a matter of your userland app via /dev/ircomm0

now I know why it didn't work out of the box for me...
this is what I get in the dmesg log:

IrDA (tm) Protocols for Linux-2.2 (Dag Brattli)
irda_setup timed out on 1st byte
irda_setup timed out on 1st byte
IrDA: Registered device irda0
irtty_net_open()
irlap_change_speed(), setting speed to 9600

I looked at macserial.c, the "irda_setup timed out on 1st byte" is printed
if the chip doesn't give a proper response until the timeout finishes.
i tried increasing the timeout from 10ms to 20ms, but it didn't help.

so, the irda setup supposedly fails. (it branches to a label called "out",
but I didn't look the code much further...) so, this is on a Pismo
PowerBook, with kernel 2.2.17pre20-ben3, macserial.c compiled in the
kernel, other things are modules (like irda.o, ircomm.o, ircomm-tty.o,
irtty.o) however, I don't know what is the main difference between ircomm
and irtty, I couldn't find an explanation good enough anywhere, anyway
which one of these is supposed to work on PowerBooks?
