"""
|
|
Receive-side station emulator for connect frame tests over a high quality simulated audio channel.
|
|
|
|
Near end-to-end test for sending / receiving connection 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.
|
|
|
|
Invoked from test_modem.py.
