L2CONTROL(8) BSD System Manager's Manual L2CONTROL(8)NAME
l2control -- L2CAP configuration utility
SYNOPSIS
l2control [-hn] -a local command [parameters ...]
DESCRIPTION
The l2control utility connects to the local device with the specified BD_ADDR or name and attempts to send the specified command. The
l2control utility will print results to the standard output and error messages to the standard error output.
The options are as follows:
-a local
Connect to the local device with the specified BD_ADDR or name. Example: -a 00:01:02:03:04:05 or -a bt_device.
-h Display usage message and exit.
-n Show Bluetooth addresses as numbers. Normally l2control attempts to resolve Bluetooth addresses, and display them symbolically.
command
One of the supported commands (see below). The special command help can be used to obtain a list of all supported commands. To get
more information about a specific command use help command.
parameters
One or more optional space separated command parameters.
COMMANDS
The currently supported node commands in l2control are:
Read_Node_Flags
Read_Debug_Level
Write_Debug_Level
Read_Connection_List
Read_Channel_List
Read_Auto_Disconnect_Timeout
Write_Auto_Disconnect_Timeout
EXIT STATUS
The l2control utility exits 0 on success, and >0 if an error occurs.

L2PING(8) BSD System Manager's Manual L2PING(8)NAME
l2ping -- send L2CAP ECHO_REQUEST to remote devices
SYNOPSIS
l2ping [-fhn] -a remote [-c count] [-i wait] [-S source] [-s size]
DESCRIPTION
The l2ping utility uses L2CAP ECHO_REQUEST datagram to elicit an L2CAP ECHO_RESPONSE datagram from a remote device.
The options are as follows:
-a remote
Specify the remote device to ping. The remote device can be specified by either its BD_ADDR or name. If name was specified then the
l2ping utility will attempt to resolve the name via bt_gethostbyname(3).
-c count
Number of packets to send. If this option is not specified, l2ping will operate until interrupted.
-f Do not wait between sending each packet.
-h Display usage message and exit.
-i wait
Wait wait seconds between sending each packet. The default is to wait for one second between each packet. This option is ignored if
-f has been specified.
-n Numeric output only. No attempt will be made to look up symbolic names for host addresses.
-S source
Specify the local device which should be used to send L2CAP ECHO_REQUEST datagrams. The local device can be specified by either its
BD_ADDR or name. If name was specified then the l2ping utility will attempt to resolve the name via bt_gethostbyname(3).
-s size
Specify the number of payload bytes to be sent. The default size is 44 bytes. It is calculated as minimum L2CAP MTU (48 bytes)
minus the size of the L2CAP signalling command header (4 bytes). The maximum size is 65531 bytes. Is is calculated as maximum L2CAP
MTU (65535 bytes) minus four bytes of payload reserved for l2ping internal use. Use this option with caution. Some implementations
may not like large sizes and may hang or even crash.
EXIT STATUS
The l2ping utility exits 0 on success, and >0 if an error occurs.

BUGS
Could collect more statistic. Could check for duplicated, corrupted and lost packets.

Originally, we only had one shell on unix. When ran a command, the shell would attempt to invoke one of the exec() system calls on it. It the command was an executable, the exec would succeed and the command would run. If the exec() failed, the shell would not give up, instead it... (3 Replies)

In this case will the 1 gb of heap memory be returned... (9 Replies)
