protocon 1.4.0

Description:

protocon 1.4.0

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.

Trans(script) Mode
When starting Protocon, one or more resource files containing commands
can be specified and will be executed in sequence.
