mm yes, my bad

what extra do you need to control with the ioctl() ?

(I think your direction is wrong and it may be unnecessary - see below)

my thought is that for example, add

--- btattach.c  6 Dec 2009 12:55:46 -0000       1.5
+++ btattach.c  19 Jan 2010 12:23:03 -0000
@@ -97,6 +97,12 @@
        .speed = B9600,
     },
     {
+       .name = "dtl",
+       .line = "btdtl",
+       .descr = "Nokia DTL-1/4",
+       .speed = B115200,
+    },
+    {
        .name = "ericsson",
        .line = "btuart",
        .descr = "Ericsson based modules",


and then

# btattach -f dtl /dev/tty01

will call

        ioctl(fd, TIOCSLINED, "btdtl")

and the "btdtl" line driver handles accumulating the packets in the
correct manner and passing it to the netbt stack.  I think btuart.c is
unnecesssary for this device to work? The protocol used is different..

and if some extra ioctl() is required for this protocol driver, it would
be defined in "btdtl.h" .. (but probably not needed)
