required input values. At the same time a graphic of
the input parameters is displayed in the right screen
window. The parameter that is requested in the
dialog prompt is highlighted

Enter all parameters requested by the TNC and

conclude each entry with the ENT key

The TNC ends the dialog when all required data has

been entered
