FreeDATA is a fully network based application. This brings as some options how we can use the entire application suite.
FreeDATA consists of 3 applications:
This is the user interface which allows changing settings easily
This is the TNC - it is a command line interface application and contains the modem related parts. The modulation will be created there and also the ARQ protocol is part of the tnc
The daemon is a command line interface application as well but its just a helper for starting and stopping the TNC remotely. When running from app bundle, you don't have to care about its existence.
