This is an attempt at getting the parent device to be bound to the sysfs
entry of rfcomm tty.
This let hal detect it properly when connecting. No more.
Thus one have to :
$ rfcomm connect 0
after adding his configuration for the device to connect to in
/etc/bluetooth/rfcomm.conf
One need a patch to hal (for to add the address and channel data to the
hald/linux/device.c serial handler) and an fdi for to add the
capabilities to get the serial line to be recognized as a modem by
NetworkManager.
Maybe it could be achieved at bind. Though this would either requires a
change to rfcomm to get the sysfs data available at bind and not connect
or to have hal poll bluez (I don't know yet if udev send event at rfcomm
bind /dev/rfcommX creation so if polling could be avoided).
Also this does not address the lack of presence of rfcomm tty in
/sys/devices. This I am too lost in the different device_move to know if
it is registered in /sys/devices then moved to /sys/class/bluetooth or
if something is missing for to get the entries in /sys/devices . Tty
available documentation implying it should be automatic lead me to think
device_move is the key of this issue.
So it is not a panacea but with this at least it becomes "possible" to
get something out of hal and with a single script that rfcomm connect to
get the bluetooth serial device in NetworkManager.
