LINE_ADDRESSSTATE The LINE_ADDRESSSTATE message gets sent when the status of an address changes on a line that is currently open by the application. The application can invoke lineGetAddressStatus to determine the current status of the address.

LINEADDRESSSTATE_INUSEZERO The address changed to idle (it is now in use by zero stations). LINEADDRESSSTATE_INUSEONE The address changed from idle or from being used by many bridged stations to being used by just one station.
