Pyaudio runs into error, because audio device is still blocked after closing program

We want to have clean audio. If it's too loud, we can't decode that well

At poor channels we have problems with signalling frames.

Initial PING or OPEN DATACHANNEL: send signalling once,
PING ACK or DATA CHANNEL ACK etc.: send signalling twice

Add an additional Channel for generating noise.

Use freedv noise generator If possible

Important for CRC 16 calculation of own call to make sure, frames will only be received by designated receiver

If we are connected to the TNC and loosing network connection, display state needs to be reset to "default" / "unlocked"

Go-Back-N needed for high performance transmission
Stop-And-Wait could be interesting for low SNR transmission

CPU load high if in while state

Create a data out buffer, which is storing the last received messages.

This could be an array or data list.

Occurs on the tnc if the gui connection is getting closed for some reason.

A terminal logging output instead of an error message would be better

Connection seems to be closing after a command will be sent.

Could be because of async vs threading on the tnc on calling a command execution

Time to define some custom frames which are necessary for ACK frames...

We need a logging mode for debugging which writes the tnc cli output to a file

immediately stop transmission if needed

Programm errors on socket causes big lags of network connection. TNC should crash or affect GUI and >< <>

Transmit function is blocking. Therefore if a transmission is in progress, the socket isn't receiving data.

Debugging is ugly right now. An output with timestamps is required!

While initializing the sound device via pyaudio, the following error occurs:

OSError: [Errno -9997] Invalid sample rate

We need to detect the supported sample rate and set it dynamically via

sample_rate = p.get_device_info_by_index(0)['defaultSampleRate']

This needs also be tested if we don't get problems with FreeDV

Pyhamlib not available as pip3 release for windows and Mac.
rigctld is available as precompiled binary for Windows and Linux.

We could create a subdirectory under tnc with the binaries and starting them while opening the tnc from daemon
