This page outlines the SerialMagic engine API interface on Windows.
On Windows, the SerialMagic API is provided via an event-based interface.
The example project builds the "DirectDataTest" application which is designed to work with SerialMagic Professional 220.127.116.11 and later. To test the API first run SerialMagic Professional 18.104.22.168 or later, then in the Application Settings dialog enable the "Post Direct Data" option.
When DirectDataTest is running (below left) ensure that SerialMagic Professional is running, then tap the DirectDataTest "Register" button and it should register to receive scan events (or data packets) from SerialMagic Professional (below center). Then when data is scanned DirectDataTest should get an event with the data (below right)
