"""
|
|
Send- and receive-side station emulator for control frame tests over a high quality
|
|
simulated audio channel.
|
|
|
|
Near end-to-end test for sending / receiving 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 ModemParam.
|
|
|
|
Invoked from test_datac13.py.
