Specifies whether or not the physical connection Model is enabled or not. If this property is true, the physical connection model is enabled, and if false, it is disabled.
By setting this property as true, communication ports are opened, and communication becomes possible. However, the communication ports are actually opened not at the moment the property is set to true, but rather immediately afterward. For this reason, even if the following type of program is written, it is not possible to know whether or not the port was opened.
.PhysicalConnection = True
If .PhysicalConnection Then
PhysicalConnection As Boolean
void SetPhysicalConnection(BOOL bNewValue);
