COM connections define the loose coupling of software component instances
in the design. COM connections are mainly used for communication between application modules,
in contrast to API interfaces that are used between application and the platform (OS, drivers).
The Connection Editor shows the properties of the selected COM connection.
COM type VLNV shows the COM Definition that defines the communication protocol.
A COM connection has a mandatory name and an optional description. By default, the connection is named by the connected instances and interfaces.
