Name
       rfcomm - RFCOMM configuration utility

SYNOPSIS
       rfcomm [OPTIONS]  

DESCRIPTION
       rfcomm(1)  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.

OPTIONS
       -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  | 
	      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 authentication

       -E     Enable encryption

       -S     Secure connection

       -C     Become the central of a piconet

       -L 
	      Set linger timeout

COMMANDS
       show 
	      Display the information about the specified device.

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

       listen  [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  [channel] [cmd]
	      Watch is identical to listen except that when the child process terminates or the client disconnect, the	com‐
	      mand will restart listening with the same parameters.

       bind  [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 
	      This command releases a defined RFCOMM binding.

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