RFCOMM_SPPD(1)          NetBSD General Commands Manual          RFCOMM_SPPD(1)

NAME
     rfcomm_sppd -- RFCOMM Serial Port Profile daemon

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

DESCRIPTION
     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.

     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  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.

     -s service  This is the service class that will be searched for on the
                 remote device.  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.

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

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

EXAMPLES
           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.
