"""
Test connect frame commands over a high quality simulated audio channel.
Near end-to-end test for sending / receiving connection control frames through the
Modem and modem and back through on the other station. Data injection initiates from the
queue used by the daemon process into and out of the Modem.
Can be invoked from CMake, pytest, coverage or directly.
Uses util_modem_I[RS]S.py in separate process to perform the data transfer.
