     rfcomm_sppd -- RFCOMM Serial Port Profile daemon

     rfcomm_sppd [-d device] [-m mode] [-p psm] [-s service] [-t tty]
                 {-a address | [-c channel]}

     The rfcomm_sppd utility is a Serial Port Profile daemon, providing serial
     access over an RFCOMM connection to a remote device.  rfcomm_sppd can
     work in client or server mode.

     In client mode, rfcomm_sppd initiates an RFCOMM connection to the service
     at the remote address.

     In server mode, rfcomm_sppd registers the service with the local SDP
     server and listens on the specified RFCOMM channel for an incoming con-
     nection, or the first unused channel if none was given.

     The options are as follows:

     -a address  Client mode.  Specify the address of the remote RFCOMM
                 device.  The address can be specified as BD_ADDR or name.  If
                 given as a name, then the rfcomm_sppd utility will attempt to
                 resolve the name via bt_gethostbyname(3).

     -c channel  In server mode, specify the RFCOMM channel number to listen
                 on.  rfcomm_sppd will register the service with the local
                 sdpd(8) daemon.  Note that registering services with sdpd(8)
                 is a privileged operation.

     -d device   Use the local device with the specified address.  The device
                 can be specified by BD_ADDR or device name.  See btconfig(8)
                 for a list of available devices.  If no device is specified,
                 the connection will be set up on a system determined device.

     -m mode     Set connection link mode.  Supported modes are:

                       auth          require devices be paired.
                       encrypt       auth, plus enable encryption.
                       secure        encryption, plus change of link key.

     -p psm      Specify the "Protocol/Service Multiplexer" value to be used
                 for the RFCOMM protocol.  In client mode where Service Dis-
                 covery is being used, this value will be ignored.

     -s service  Name of service class to connect to or register.  If no
                 service is given, the default "Serial Port" service class
                 will be used.  Known service classes are:

                       DUN           Dialup Networking
                       LAN           LAN access using PPP
                       SP            Serial Port

                 In client mode, the service class may be given as a channel
                 number, for instances where the remote device does not pro-
                 vide Service Discovery.

     -t tty      Slave pseudo tty name.  If this option is given, rfcomm_sppd
                 will detach from the controlling process after the Bluetooth
                 connection is made, and operate over the named pty(4) pair.
                 Otherwise, stdin/stdout will be used.

     /dev/pty[p-sP-S][0-9a-v]  master pseudo terminals
     /dev/tty[p-sP-S][0-9a-v]  slave pseudo terminals

     The rfcomm_sppd utility exits 0 on success, and >0 if an error occurs.

           rfcomm_sppd -a 00:01:02:03:04:05 -s 1 -t /dev/ttyp1

     Will open an RFCOMM connection to the server at 00:01:02:03:04:05 on
     channel 1.  Once the connection has been established, rfcomm_sppd will
     detach and /dev/ttyp1 can be used to communicate with the remote serial
     port on the server, e.g. with the use of

           cu -l /dev/ttyp1

     In order to use rfcomm_sppd to automatically create a secured link for
     pppd(8), use
           pty "rfcomm_sppd -a 00:01:02:03:04:05 -s DUN -m secure"

     in your pppd(8) configuration file.

     The rfcomm_sppd program first appeared in FreeBSD and was ported to
     NetBSD 4.0 by Iain Hibbert under the sponsorship of Itronix, Inc.
