BTATTACH(8)                 System Manager's Manual                BTATTACH(8)

NAME
     btattach - attach serial lines as Bluetooth HCI interfaces

SYNOPSIS
     btattach [-dFfoPp] [-i speed] [type] tty speed
     btattach -t [-dFfoPp] tty

DESCRIPTION
     btattach is used to assign a tty line to a Bluetooth Host Controller
     Interface using the btuart(4) or bcsp(4) line disciplines, and can
     optionally initialize the line for a given device type before activating
     the line discipline.

     Supported types are:
           bcm2035          Broadcom BCM2035
           bcm43xx          Broadcom BCM43xx
           bcm43xx-3wire    Broadcom BCM43xx (3-wire)
           bcsp             Generic BCSP (BlueCore Serial Protocol)
           bgb2xx           Philips BGB2xx module
           btuart           Generic UART (this is the default)
           csr              Cambridge Silicon Radio Casira serial adapter, or
                            Brainboxes serial dongle (BL642)
           ericsson         Ericsson based modules
           digi             Digianswer based cards
           st               ST Microelectronics minikits based on
                            STLC2410/STLC2415
           stlc2500         ST Microelectronics minikits based on STLC2500
           swave            Silicon Wave kits
           texas            Texas Instruments modules
           unistone         Infineon UniStone (PBA31308) modules

     When the line discipline is activated, btattach detaches and sleeps until
     it receives a SIGHUP.

     The command line options are as follows:

     -d              debug mode.  print initialization IO and do not detach.

     -F              Disable flow control.

     -f              Enable flow control.

     -i speed        Specify an alternate speed for the Bluetooth module to
                     use during the initialization phase.

     -o              Enable odd parity.

     -P              Disable parity.

     -p              Enable parity (even parity).

     -t              Test mode.

     Only the super-user may attach a Bluetooth HCI interface.

     Test mode tries to guess the speed using the received link-establish
     packet from HCI, or btuart(4), if there is no response.
