rfcomm - RFCOMM configuration utility


   rfcomm [ options ] < command > < dev >


   rfcomm   is   used   to  set  up,  maintain,  and  inspect  the  RFCOMM
   configuration of the Bluetooth subsystem in the  Linux  kernel.  If  no
   command  is  given,  or  if  the  option  -a  is  used,  rfcomm  prints
   information about the configured RFCOMM devices.


   -h     Gives a list of possible commands.

   -a     Prints information about all configured RFCOMM devices.

   -r     Switch TTY into raw mode (doesn't work with "bind").

   -i <hciX> | <bdaddr>
          The command is applied to device 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.

   -A     Enable authentification

   -E     Enable encryption

   -S     Secure connection

   -M     Become the master of a piconet

   -L <seconds>
          Set linger timeout


   show <dev>
          Display the information about the specified device.

   connect <dev> [bdaddr] [channel]
          Connect the RFCOMM device to the remote Bluetooth device on  the
          specified  channel.  If no channel is specified, it will use the
          channel number 1. This command can be terminated  with  the  key
          sequence CTRL-C.

   listen <dev> [channel] [cmd]
          Listen  on  a specified RFCOMM channel for incoming connections.
          If no channel is specified, it will use the  channel  number  1,
          but  a channel must be specified before cmd. If cmd is given, it
          will be executed as soon as a client connects.  When  the  child
          process  terminates  or  the client disconnect, the command will
          terminate.  Occurrences of {} in cmd will  be  replaced  by  the
          name  of  the device used by the connection. This command can be
          terminated with the key sequence CTRL-C.

   watch <dev> [channel] [cmd]
          Watch is identical to listen except that when the child  process
          terminates  or  the  client disconnect, the command will restart
          listening with the same parameters.

   bind <dev> [bdaddr] [channel]
          This binds the RFCOMM device to a remote Bluetooth  device.  The
          command does not establish a connection to the remote device, it
          only creates the binding. The  connection  will  be  established
          right  after  an application tries to open the RFCOMM device. If
          no channel number is specified, it uses the channel number 1.

   release <dev>
          This command releases a defined RFCOMM binding.

          If all is specified for the RFCOMM  device,  then  all  bindings
          will be removed.
