Hi all,
if you started
rfcomm x XXXXXXXXXX y &
and the connection to XXXXXXXXXXX is running,
How can other application terminate that connection (much like pand -k addr)
What API (ioctl ?) should be used ? Code samples ?>

the use of ACL connections is tracked with reference counting and as
long as there is a upper layer connection using the ACL link it is not
closed. If the last one is gone, the disconnect timer is started and
after the timeout the ACL link is terminated.
I hope you asked for this otherwise I don't understand your question.
Regards
Marcel

I want to create a 'hangup' button that should disconnect from
a phone connection immediately. This means that is
should terminate say the ppp connection ontop of the serial
connection and also the serial connection to the phone.
What you say is that if I close the ppp after a while the rfcomm
connection would stop automatically. That is nice but that is
not what I want.
So I am looking for an equivalent to pressing CTRL-C in the
controlling terminate of the running rfcomm daemon using a
C-API call.
Is that more clear ?
Thanx

this makes it even more unclear to me. You talked about PAN and RFCOMM.
What profiles do you wanna serve? What is your current setup?

OK let's start again.
if I run the command rfcomm 0 xxxxx 1 under a linux shell,
the rfcomm program starts up and (if run in background) runs
as a connection daemon between a device file /dev/xxx and a RFCOMM
connection to - say - a telephone.
On top of that rfcomm device file (/dev/xxx) you can run a pppd and
hence create a GPRS connection over that phone.
now suppose I want to disconnect from that GPRS connection. First I need
to terminate the ppp connection. This is easy : just kill pppd.
Next I need to disconnect from the phone. I.e. terminate the serial
connection that the rfcomm daemon is managing.
I could kill the 'appropriate' rfcomm daemon. However since the PAND
daemon serves a very similar purpose and you can call PAND with -k
to terminate a certain NAP/PANU - BNEP connection without having
to kill that PAND I was wondering if there is a similar call for RFCOMM.
The source for PAND shows that calling
ioctl(ctl, bnepconndel, .... )
terminates a certain BNEP connection.
Does RFCOMM have a similar API e.g.
iotcl( ctl, rfcommconndel, ... ) ?

you should use "rfcomm bind 0 ..." and simply open /dev/rfcomm0. If the
last user of /dev/rfcomm0 is gone and nobody else is using the ACL link
between these devices it will disconnect. These means kill the pppd
terminates the RFCOMM connection and in the end the ACL link.

the BNEP and RFCOMM have actually nothing in common. Their design it
quite different. If you wan't something similar then you must play with
dund.
