RoboSHOT HD Camera Systems Exit NAME exit - ends the current API command session SYNOPSIS exit DESCRIPTION Exit ends the current API command session. If the session is over telnet, the session is ended and the socket is closed. If the session is over serial, a new session is started. Help NAME help - display an overview of the CLI syntax SYNOPSIS help DESCRIPTION Display an overview of the command line syntax History NAME history - command history SYNOPSIS history [limit] DESCRIPTION Since many of the programs read user input a line at a time, the command history is used to keep track of these lines and also recall historic information HISTORY NAVIGATION The command history can be navigated using the up and down arrow keys. The up arrow will move up a single entry in the command history while the down arrow moves down in the command history. HISTORY EXPANSION The command history supports the expansion functionality from which previous commands can be recalled from within a single session. History expansion is performed immediately after a complete line is read. Listed below are examples of history expansion: * !! Substitute the last command line. * !N Substitute the Nth command line (absolute as per 'history' command) * !-N Substitute the command line entered N lines before (relative) EXAMPLES history Displays the current command buffer history 5 Sets the history command buffer to remember the last 5 unique entries Network Ping NAME network ping - send ICMP ECHO_REQUEST to network hosts SYNOPSIS network ping [count ] [size ] DESCRIPTION Use the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams have an IP and ICMP header, followed by a struct timeval and then an arbitrary number of pad bytes used to fill out the packet. OPTIONS count Stop after sending count ECHO_REQUEST packets. With deadline option, ping waits for count ECHO_REPLY packets, until the timeout expires. The default is 5. destination The destination IP address where the ECHO_REQUESTS are sent size The data size of the ICMP packet to send. The default is 56 bytes EXAMPLES network ping 192.168.1.1 Attempt to send 5 ICMP ECHO_REQUESTs with data size 56 to the host at 192.168.1.1 network ping count 10 size 100 192.168.1.1 Attempt to send 10 ICMP ECHO_REQUESTs with data size of 100 to the host at 192.168.1.1 RoboSHOT HD Cameras, Document Number 342-0793 Page 52 of 60
