 Commander can have up to three Stream objects connected at once, an input stream, output stream and auxiliary stream. As well as reading commands and passing them to the handler functions Commander can route or copy data to another port, echo data back to you and redirect or copy responses to a different port. When using SD Cards and the SDFat library, Commanders input Stream can be attached to one file to read commands, the output Stream can be attached to a second file for logging any responses generated by the command handler, and the aux stream can copy all those responses to a serial port.

-It allows you to define a list of text commands, a function to handle each command, and some help text that can be displayed when the 'help' command is sent. All the work of reading the incoming stream data, identifying the appropriate function and calling the handler is done by the commander object. It will run on most Arduino boards but is more suited to devices with large memory.

-Commander is attached to Stream object so it can be used with Serial ports, files on a SD cards, or Bluetooth Serial and other Stream based objects on wireless capable Arduinos such as the ESP32.

 Commander is designed so that the list of commands, handlers and help text are separate from the Commander object, this allows command lists to be shared between several instances of a Commander object, for example where the same command set needs to be available via USB and Bluetooth Serial. It also allows different command lists to be dynamically loaded so multiple command lists, and multiple Commander objects can be combined to produce hierarchical command structures.
 
 Commands can be chained together in a single line and Commander incorporates a set of functions for extracting any payload that comes after a command and for sequentially parsing variables in the payload. It can also augment responses sent to its output and auxiliary Streams by adding prefix and postfix text, for example each line can be enclosed with opening and closing html tags, or prefixed with a command.
