If, for example, the wheel is now rotated, the Callback function of the Keto-
pAPI is called automatically. There, a Windows message is sent, and re-
ceived and processed by the test tool application which, in this case, is
synonymous with a graphical update of the tab that is currently active. This
modified value is then sent to the control by a write command.
The started timer cyclically informs the control that it would like to read. The
control calls the Callback function registered with it and thus triggers a
Window message. This, in turn, is received by the application. In the next
step, a read command is sent to the control and the tab that is currently ac-
tive is determined. The modified values are handed over to this tab and
only this tab carries out an update of the screen.
General procedure for communicating with the control using the SerCp001.dll
1. Load the library (SerCp001.dll)

3. Install the Callback function
4. Open and configure the port
