oec

oec is an open replacement for the IBM 3174 Establishment Controller.

It is a work in progress - as of now it only provides basic TN3270 and VT100 emulation.

Usage

You will need to build a interface and connect it to your computer.

Then configure a Python virtual environment and install dependencies:

python -m venv VIRTUALENV
. VIRTUALENV/bin/activate
pip install -r requirements.txt --no-deps

Assuming your interface is connected to /dev/ttyUSB0 and you want to connect to a TN3270 host named mainframe:

python -m oec /dev/ttyUSB0 tn3270 mainframe

If you want to use the VT100 emulator and run /bin/sh as the host process:

python -m oec /dev/ttyUSB0 vt100 /bin/sh -l
