Hello

I'm trying to connect to my new mobile phone via a usb bluetooth 
dongle. I solved many problems (and learned a lot) but I'm 
stuck. I downloaded and installed the latest bluez stuff. 
(Version 2.16 at this time) It seems to work but I still can not 
comminicate with my phone. I can start everything and could pair 
my phone with my PC. When I start minicom to test the 
connection, I can type anything but phone answers with "error". 
I tried it with hyperterminal under windows and it works. So we 
shouldn't talk about hardware problems.

Here is my hciconfig -a output:

And here is the "hcidump -x" result when I enter an "atz" modem 
command in minicom:

      09 EF 13 0D 0A 45 52 52 4F 52 0D 0A 40

I noticed in the last line that there was "09 ef 13" echoed back 
instead of "atz". So I can understand why the modem says error 
but I can't understand how can it receive these characters.

What I missed? Can anybody help?
