Detailed Description

Simulates the behavior of an antenna interface.

The class Mount is a good example of a component and simulates the behaviour of an antenna interface. It provides two asynchronous methods: objstar and objfix. The methods only write the data into virtual properties instead of hardware. Asynchronous calls are implemented using the ...... pattern and the ..... support classes. For each xxx action defined in the IDL interface two methods are provided:
