"""
Send-side station emulator for test frame tests over a high quality audio channel
using a physical sound card or STDIO.
Legacy test for sending / receiving connection test frames through the codec2 and
back through on the other station. Data injection initiates directly through
the codec2 API.
Invoked from CMake, test_highsnr_stdio_{P_C, P_P}_datacx.py, and many test_virtual[1-3]*.sh.
