protocon 1.0.1

Protocon is a socket-centric framework for rapidly prototyping connections through simple send and receive transcripts.

Protocon is a socket-centric framework for rapidly prototyping connections through simple send and receive commands. Think socat with pretty hex output and more send / receive automation control.

Installing

Protocon requires Python 3.4+ and can be installed via pip using the command python3 -m pip install protocon.

Example Usage

Manual Mode

Starting Protocon requires a target_url argument which describes the type of socket to open and the endpoint to connect to. Protocon will then switch to an interactive console where various commands are available to send and receive data.
