rfcomm problems

Hello,

i'm trying to setup a bluetooth gprs connection.
the problem is that the connection works
only if i start rfcomm_sppd on a TTY, 
and then start manually ppp with "set device" the 
same TTY.
rfcomm_pppd and rcomm_sppd with stdin/stdout
does not work properly as the bluetooth modem
echoes everyting back.
I get the same results with the bluetooth modems
on a Nokia 6230 phone and Motorola RazrV3.

Here is exactly what happens when i start rfcomm_sppd on console :
-------------------
root_at_phobos# rfcomm_sppd -a gsm -c 1
rfcomm_sppd[2628]: Starting on stdin/stdout...
atz
atz
atz
atz
ate0
ate0
^Crfcomm_sppd[2628]: Signal 2 received. Total 1 signals received
rfcomm_sppd[2628]: Completed on stdin/stdout
------------------
(i typed two times atz, and one time ate0 and it was echoed right back)

When i start rfcomm_pppd the ppp daemon begins to write in the log
that he is talking to himself (several "magic is same" errors, and disconnect)

But when i start rfcomm_sppd in the background on a tty
it is working properly:
------------------
root_at_phobos# rfcomm_sppd -a gsm -c 1 -b -t /dev/ttyp0
root_at_phobos# cu -l /dev/ttyp0
Connected
atz
OK

[EOT]
------------------

I'm running about one week old 7.0-CURRENT but
have experienced this for quite some time.
Also, i'm using a usb bluetooth dongle,
and the /etc/rc.bluetooth init script.

does anyone have idea what can be causing this?
