btuart and SOCKET Bluetooth CF
Hi! Iain and all,
I am supporting NOKIA DTL-1/4 now.
(SOCKET Bluetooth CF 8510-00159F and older version)
Linux supported it by drivers/bluetooth/dtl1_cs.c.
This obtains BDADDR now and does inquiry. However, this should attach/
detach the 4byte header at btuart.
The support of DTL can change some parameters. I think that ioctl is
necessary for that.

Should we support ioctl for this? Or, do you have a better idea?
Thanks,
