* | |||
* Sequencer can automate communication with a terminal-like device such as AT-command modems etc... | |||
* Sequencer is a script engine with receive/transmit functionalities based on predicates. It has: | |||
* - A program counter like variable named \c step. | |||
* - \c step actions like NEXT, GOTO exit with status etc... | |||
* - Input data match predicates to trigger those actions. | |||
* - Input data handlers to trigger external functionality on predicate match | |||
* - Output data handlers to "edit" data before transmiting them | |||
* - A small predicate set provided to the user. (starts_with, ends_with, contains). | |||
* | |||
* Sequencer can automate communication with a terminal-like device such as AT-command modems, can | |||
* be used to implement communication protocols, or even small http servers. | |||
* | |||
* It can operate based on a script array and handle the outgoing commands and incoming responses. | |||
* The user can create matching rules on received data and hook handlers and actions on them. | |||
* | |||
* The derived class (implementation) has to provide: | |||
* 1) size_t get(Data_t* data); | |||
* This function return 0 or a number of Data_t items. The data points to buffer for the input data. | |||
