Net::CLI::Interact::Transport::Serial - Serial-line based CLI connection VERSION
version 1.121640 DECRIPTION
This module provides a wrapped instance of a Serial-line client for use by Net::CLI::Interact. INTERFACE
app On Windows platforms you must download the "plink.exe" program, and pass its location to the library in this parameter. On other platforms, this defaults to "cu", which again you must download and install. runtime_options Based on the "connect_options" hash provided to Net::CLI::Interact on construction, selects and formats parameters to provide to "app" on the command line. Supported attributes: FIXME: on Windows platforms, only the device attribute is supported. device (required) Name of the device providing access to the Serial-line (e.g. "/dev/ttyUSB0" or "COM5". parity You have a choice of "even", "odd" or "none" for the parity used in serial communication. The default is "none". nostop You can control whether to use "XON/XOFF" handling for the serial communication. The default is to disable this, so to enable it pass any True value. speed You can set the speed (or baud rate) of the serial line by passing a value to this named parameter. The default is 9600. reap Only used on Unix platforms, this installs a signal handler which attempts to reap the "ssh" child process. Pass a true value to enable this feature only if you notice zombie processes are being left behind after use. COMPOSITION

Net::CLI::Interact::Role::Prompt(3pm) User Contributed Perl Documentation Net::CLI::Interact::Role::Prompt(3pm) NAME
Net::CLI::Interact::Role::Prompt - Command-line prompt management VERSION
version 1.121640 DESCRIPTION
This is another core component of Net::CLI::Interact, and its role is to keep track of the current prompt on the connected command line interface. The idea is that most CLI have a prompt where you issue commands, and are returned some output which this module gathers. The prompt is a demarcation between each command and its response data. Note that although we "keep track" of the prompt, Net::CLI::Interact is not a state machine, and the choice of command issued to the connected device bears no relation to the current (or last matched) prompt. INTERFACE
set_prompt( $prompt_name ) This method will be used most commonly by applications to select and set a prompt from the Phrasebook which matches the current context of the connected CLI session. This allows a sequence of commands to be sent which share the same Prompt. The name you pass in is looked up in the loaded Phrasebook and the entry's regular expression stored internally. An exception is thrown if the named Prompt is not known. Typically you would either refer to a Prompt in a Macro, or set the prompt you are expecting once for a sequence of commands in a particular CLI context. When a Macro completes and it has been defined in the Phrasebook with an explicit named Prompt at the end, we can assume the user is indicating some change of context. Therefore the "prompt" is automatically updated on such occasions to have the regular expression from that named Prompt. prompt_re Returns the current Prompt in the form of a regular expression reference. The Prompt is used as a default to catch the end of command response output, when a Macro has not been set up with explicit Prompt matching. Typically you would either refer to a Prompt in a Macro, or set the prompt you are expecting once for a sequence of commands in a particular CLI context. unset_prompt Use this method to empty the current "prompt" setting (see above). The effect is that the module will automatically set the Prompt for itself based on the last line of output received from the connected CLI. Do not use this option unless you know what you are doing. has_set_prompt Returns True if there is currently a Prompt set, otherwise returns False. prompt_looks_like( $name ) Returns True if the current prompt matches the given named prompt. This is useful when you wish to make a more specific check on the current prompt. find_prompt( $wake_up? ) A helper method that consumes output from the connected CLI session until a line matches any one of the named Prompts in the loaded Phrasebook, at which point no more output is consumed. As a consequence the "prompt" will be set (see above). This might be used when you're connecting to a device which maintains CLI state between session disconnects (for example a serial console), and you need to discover the current state. However, "find_prompt" is executed automatically for you if you call a "cmd" or "macro" before any interaction with the CLI. The current device output will be scanned against all known named Prompts. If nothing is found, the default behaviour is then to send the content of our "wake_up" slot (see below), and try to match again. The idea is that by sending one carriage return, we might be sent a new prompt. If you wish to disable this behaviour, pass a false value into this method. wake_up Text sent to a device within the "find_prompt" method if no output has so far matched any known named Prompt. Default is the value of the output record separator from the Transport (one newline). last_prompt Returns the Prompt which most recently was matched and terminated gathering of output from the connected CLI. This is a simple text string. last_prompt_re Returns the text which was most recently matched and terminated gathering of output from the connected CLI, as a quote-escaped regular expression with line start and end anchors.
