[bluetooth-dev] Cannot run stack in kernal mode.



I use openbt 0.0.8 on slakware 8.1 with ericsson bluetooth application & 
training tool kit. I try to run btdm. But it will hang and show the message

root@xxxxxxx./btdm -u /dev/ttyS2 -R
Please reset HW board within 5 seconds

So I change to run "btd" instead. I run it on 2 linux PC.
./btd -R -u /dev/ttyS2 -m and
./btd -R -u /dev/ttyS1 -m -r client
Everything seem no error. But when I try to use command "inq <Max number of 
responses> (inquiry scan)" it cannot find another bluetooth device like 
this.

>inq 3 3
Inquiry: Timer expired

I don't know what i am wrong. Can anyone tell me what should I do?
Thank everybody
Best regard.
