"""
|
|
Test control frame messages over a high quality simulated audio channel.
|
|
|
|
Near end-to-end test for sending / receiving select control frames through the
|
|
TNC 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 TNC.
|
|
|
|
Can be invoked from CMake, pytest, coverage or directly.
|
|
|
|
Uses util_datac0.py in separate process to perform the data transfer.
