     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

     In server mode, rfcomm_sppd registers the service with the local SDP server and listens on
     the specified RFCOMM channel for an incoming connection, 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 util-
		 ity 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

     -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 pro-
		 tocol.  In client mode where Service Discovery is being used, this value will be

     -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 provide 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 com-
     municate 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.
