+.Ar speed
+.Nm
+.Fl t
+.Op Fl dFfoPp
+.Ar tty
+.Sh DESCRIPTION
+.Nm
+is used to assign a
+.Ar tty
+line to a Bluetooth Host Controller Interface using the
+.Xr btuart 4
+or
+.Xr bcsp 4
+line disciplines, and can optionally initialize the line for a
+given device
+.Ar type
+before activating the line discipline.
+.Pp
+Supported types are:
+.Bl -tag -compact -width 15n -offset indent
+.It Cm bcm2035
+Broadcom BCM2035
+.It Cm bcm43xx
+Broadcom BCM43xx
+.It Cm bcm43xx-3wire
+Broadcom BCM43xx (3-wire)
+.It Cm bcsp
+Generic BCSP (BlueCore Serial Protocol)
+.It Cm bgb2xx
+Philips BGB2xx module
+.It Cm btuart
+Generic UART (this is the default)
+.It Cm csr
+Cambridge Silicon Radio Casira serial adapter, or
+Brainboxes serial dongle (BL642)
+.It Cm ericsson
+Ericsson based modules
+.It Cm digi
+Digianswer based cards
+.It Cm st
+ST Microelectronics minikits based on STLC2410/STLC2415
+.It Cm stlc2500
+ST Microelectronics minikits based on STLC2500
+.It Cm swave
+Silicon Wave kits
+.It Cm texas
+Texas Instruments modules
+.It Cm unistone
+Infineon UniStone (PBA31308) modules
+.El
+.Pp
+When the line discipline is activated,
+.Nm
+detaches and sleeps until it receives a
+.Dv SIGHUP .
+.Pp
+The command line options are as follows:
+.Bl -tag -width ".Fl i Ar speed"
+.It Fl d
+debug mode.
+print initialization IO and do not detach.
+.It Fl F
+Disable flow control.
+.It Fl f
+Enable flow control.
+.It Fl i Ar speed
+Specify an alternate
+.Ar speed
+for the Bluetooth module to use during the initialization phase.
+.It Fl o
+Enable odd parity.
+.It Fl P
+Disable parity.
+.It Fl p
+Enable parity (even parity).
+.It Fl t
+Test mode.
+.El
+.Pp
+Only the super-user may attach a Bluetooth HCI interface.
+.Pp
+Test mode tries to guess the speed using the received link-establish
+packet from HCI, or
+.Xr btuart 4 ,
+if there is no response.
