33 .Nd Netgraph node type that is also a 3Com Bluetooth PC card driver
36 .In netgraph/bluetooth/include/ng_bt3c.h
40 node type is both a persistent Netgraph node type and a driver for the
41 3Com Bluetooth PC card (3CRWB6096-HP).
42 It implements a Bluetooth HCI
43 UART transport layer as per chapter H4 of the Bluetooth Specification
45 A new node is created when the card is plugged.
47 In order to use the card one
49 download the firmware first.
50 Due to copyright issues the firmware cannot be provided with this driver.
51 The firmware can be obtained
52 from the Windows driver package that can be downloaded from the 3Com web
56 To load the firmware into the card, use
58 I am using the original firmware that came with the card on CD-ROM.

80 Incoming bytes received on the device are re-assembled into HCI frames
81 (according to the length).
82 Full HCI frames are sent out on the hook.

102 .It Dv NGM_BT3C_NODE_GET_STATE
103 Returns the current receiving state for the node.
104 .It Dv NGM_BT3C_NODE_GET_DEBUG
105 Returns an integer containing the current debug level for the node.
106 .It Dv NGM_BT3C_NODE_SET_DEBUG
107 This command takes an integer argument and sets the current debug level
109 .It Dv NGM_BT3C_NODE_GET_QLEN
110 This command takes a parameter that specifies queue number and returns
111 the current length of the queue for the node.
112 .It Dv NGM_BT3C_NODE_SET_QLEN
113 This command takes two parameters that specify the queue number and
114 the maximum length of the queue and sets the maximum length of the queue for
116 .It Dv NGM_BT3C_NODE_GET_STAT
117 Returns various statistic information for the node, such as: number of
118 bytes (frames) sent, number of bytes (frames) received and number of
119 input (output) errors.
120 .It Dv NGM_BT3C_NODE_RESET_STAT
121 Reset all statistic counters to zero.
