A method of determining when queued data becomes expendable is disclosed. An application allowing remote control telephone access to a desktop (host) computer must mirror the host's display screen. A "display monitor" periodically makes a copy of a host's display buffer and compares it with the display screen of a remote computer. The data is analyzed to find changes that have occurred. The data that has changed is enqueued to be sent to the remote computer as a display update.
