Has been seen to work on several cards and communicating with several mobile phones to use them as modems etc. We are still talking with 3com to try get them to allow us to include the firmware for their pccard in the driver but the driver is here.. In the mean time it can be downloaded from the 3com website and loaded using the utility bt3cfw(8) (supplied) (instructions in the man page) Not yet linked to the build Submitted by: Maksim Yevmenkin <myevmenk@exodus.net> Approved by: re

|
.Nm h4
|
|
.Nd Netgraph node type that is also a H4 line discipline
|
|
.Sh SYNOPSIS
|
|
.In sys/types.h
|
|
.In sys/ttycom.h
|
|
.In netgraph/ng_message.h
|
|
.In netgraph/ng_h4.h
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
node type is both a persistent Netgraph node type and a H4 line
|
|
discipline. It implements a Bluetooth HCI UART transport layer as
|
|
per chapter H4 of the Bluetooth Specification Book v1.1. A new
|
|
node is created when the corresponding line discipline,
|
|
.Dv H4DISC ,
|
|
is registered on a tty device (see
|
|
.Xr tty 4 ) .
|
|
.Pp
|
|
The node has a single hook called
|
|
.Dv hook .
|
|
Incoming bytes received on the tty device are re-assembled into
|
|
HCI frames (according to the length). Full HCI frames are sent out on
|
|
the hook. HCI frames received on
|
|
.Dv hook
|
|
are transmitted out on the tty device.
|
|
No modification to the data is performed in either direction.
|
|
While the line discipline is installed on a tty, the normal
|
|
read and write operations are unavailable, returning
|
|
.Er EIO .
|
|
.Pp
|
|
Information about the node is available via the netgraph
|
|
.Xr ioctl 2
|
|
command
|
|
.Dv NGIOCGINFO .
|
|
This command returns a
|
|
.Dv "struct nodeinfo"
|
|
similar to the
|
|
.Dv NGM_NODEINFO
|
|
netgraph control message.
|
|
.Sh HOOKS
|
|
This node type supports the following hooks:
|
|
.Pp
|
|
.Bl -tag -width foobar
|
|
.It Dv hook
|
|
single HCI frame contained in single
|
|
.Dv mbuf
|
|
structure.
|
|
.El
|
|
.Sh CONTROL MESSAGES
|
|
This node type supports the generic control messages, plus the following:
|
|
.Bl -tag -width foo
|
|
.It Dv NGM_H4_NODE_RESET
|
|
Reset the node.
|
|
.It Dv NGM_H4_NODE_GET_STATE
|
|
Returns current receiving state for the node.
|
|
.It Dv NGM_H4_NODE_GET_DEBUG
|
|
Returns an integer containing the current debug level for the node.
|
|
.It Dv NGM_H4_NODE_SET_DEBUG
|
|
This command takes an integer argument and sets current debug level
|
|
for the node.
|
|
.It Dv NGM_H4_NODE_GET_QLEN
|
|
Returns current length of outgoing queue for the node.
|
|
.It Dv NGM_H4_NODE_SET_QLEN
|
|
This command takes an integer argument and sets maximum length of
|
|
outgoing queue for the node.
|
|
.It Dv NGM_H4_NODE_GET_STAT
|
|
Returns various statistic information for the node, such as: number of
|
|
bytes (frames) sent, number of bytes (frames) received and number of
|
|
input (output) errors.
|
|
.It Dv NGM_H4_NODE_RESET_STAT
|
|
Reset all statistic counters to zero.
|
|
.El
|
|
.Sh SHUTDOWN
|
|
This node shuts down when the corresponding device is closed
|
|
(or the line discipline is uninstalled on the device).
|
|
.Sh BUGS
|
|
This node still uses spltty() to lock tty layer. This is wrong.

|
|
node type was implemented in
