     rfcomm_sppd -- RFCOMM Serial Port Profile daemon


     rfcomm_sppd [-bh] -a address -c channel [-t tty]


     The rfcomm_sppd utility is a Serial Port Profile daemon.  It opens RFCOMM
     connection to the specified address server and channel.  Once connection
     is established, the rfcomm_sppd utility provides access to the server's
     remote serial port via stdin/stdout or via pty(4) interface if -t option
     was specified.

     The rfcomm_sppd utility opens both master and slave pseudo terminals.
     This is done to ensure that RFCOMM connection stays open until
     rfcomm_sppd is terminated.  The data received from the master pseudo ter-
     minal are sent over the RFCOMM connection.  The data received from the
     RFCOMM connection are written into master pseudo terminal.  The applica-
     tion in its turn opens the slave pseudo terminal and operates on it just
     like it would operate over the standard serial port.

     The options are as follows:

     -a address
	     This required option specifies the address of the remote RFCOMM
	     server.  The address can be specified as BD_ADDR or name.	If
	     name was specified then the rfcomm_sppd utility will attempt to
	     resolve the name via bt_gethostbyname(3).

     -b      Detach from the controlling terminal, i.e., run in background.

     -c channel
	     This option specifies RFCOMM channel to connect to.  The channel
	     must provide Serial Port service.	If channel was not specified
	     then rfcomm_sppd utility will try to obtain RFCOMM channel via
	     Service Discovery Protocol from the server.

     -h      Display usage message and exit.

     -t tty  Slave pseudo tty name.  If not set stdin/stdout will be used.
	     This option is required if -b option was specified.


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

     Will start the rfcomm_sppd utility and open RFCOMM connection to the
     server at 00:01:02:03:04:05 and channel 1.  Once the connection has been
     established, /dev/ttyp1 can be used to talk to the remote serial port on
     the server.


     /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.
