[Bluez-users] How is pairing completed in rfcomm?

I'm working on getting my RH9 laptop to communicate with T68 (not i),
and I made
another step forward, but I can't complete the "pairing" process (
which is where the
phone picks up the identity of a PC and makes that PC "OK" for future
data operation.)

My steps:

insert card, do cardctl insert.
hciconfig hci0 up
rfcomm /dev/rfcomm0 MAC-ADDRESS 1 (1 is for DUN on this phone)

Now at this step I gave the phone the instruction to add to paired
devices, with
the option "phone accepts".

Then, I did this:

cat </dev/rfcomm0

at which point the phone displays the PC's name, then asks for a PIN.

I entered the PIN (a 4-digit code) that I had previously configured

Now the phone says "pairing..." and waits forever.

If I interrupt the cat </dev/rfcomm0 with Control-C,

then the following is seen:

1. Any output (echo, cat, etc.) to /dev/rfcomm0 produces the error
message:
"bash: /dev/rfcomm0: Operation already in progress"

2. The rfcomm command produces the message:
rfcomm0: MAC-ADDRESS channel 1 disconnecting

Marcel had advised me to update to the latest kernel - I am not in a
position to
do this immediately, and it I hope the pairing process would be able
to proceed
in any event, if I am using the correct procedure. I am using Kernel 2.
4.20-31.9,
which was current as of 04/2004; as the phone is nearly 2 years old,
I'm hoping
I can validate it's operation at least through the pairing process.

So my core question - how do I complete the pairing process, when
initiated
by the PC and accepted by the phone?
