+.TH CIPTOOL 1 "JUNE 6, 2003" "" ""
+
+.SH NAME
+ciptool \- Bluetooth Common ISDN Access Profile (CIP)
+.SH SYNOPSIS
+.BR "ciptool
+[
+.I options
+] <
+.I command
+>
+.SH DESCRIPTION
+.B ciptool
+is used to set up, maintain, and inspect the CIP configuration
+of the Bluetooth subsystem in the Linux kernel.
+.SH OPTIONS
+.TP
+.BI -h
+Gives a list of possible commands.
+.TP
+.BI -i " <hciX> | <bdaddr>"
+The command is applied to device
+.I
+hciX
+, which must be the name or the address of an installed Bluetooth
+device. If not specified, the command will be use the first
+available Bluetooth device.
+.SH COMMANDS
+.TP
+.BI show
+Display information about the connected devices.
+.TP
+.BI search
+Search for Bluetooth devices and connect to first one that
+offers CIP support.
+.TP
+.BI connect " <bdaddr> [psm]"
+Connect the local device to the remote Bluetooth device on the
+specified PSM number. If no PSM is specified, it will use the
+SDP to retrieve it from the remote device.
+.TP 
+.BI release " [bdaddr]"
+Release a connection to the specific device. If no address is
+given and only one device is connected this will be released.
+.TP 
+.BI loopback " <bdaddr> [psm]" 
+Create a connection to the remote device for Bluetooth testing.
+This command will not provide a CAPI controller, because it is
+only for testing the CAPI Message Transport Protocol.
+.SH AUTHOR
+Written by Marcel Holtmann <marcel@holtmann.org>.
