Status information calls

Status information calls retrieve status information about the connection between the client and server systems.

The status of connected servers is updated as a result of requests being flowed and protocol specific events. The status returned is the last known state of connected servers, which might not be the same as the current state.

ECI request status link calls can be synchronous or asynchronous.

There are three types of status information call:
Immediate
Requests status information to be sent to the user application immediately it becomes available.
Change
Requests status information to be sent to the user application when the status changes from some specified value. Change calls are always asynchronous.
Cancel
Cancels an earlier change call.
