Errors related to agent control activities will be represented by the AgentControl or the NotAllowed indication. When the error is due to an EventError, the TlibErrCode will be populated with AttributeErrorCode and the type will be AgentControl. NotAllowed will be used exclusively when attempting to control a server controlled port. The user supplied ReqId will be returned in the error.
