Abstract
User interfaces are distributed between a host computer 10 and an intelligent terminal 12 for communication over a telecommunications network 14 requiring minimum bandwidth. Host user interfaces 18 resident in the host computer 10 are distributed as terminal user interface objects 32 to the terminal 12. Terminal user interface objects 32 are directly manipulated on the terminal 12 and communicated on a filtered basis to the host computer 10 by a terminal port controller 34. Messages from the terminal 12 are directed by a host dispatcher 26 to host user interfaces which communicate with the host processor 16. Output messages from the host are routed through host and terminal port controllers 20 and 34, a terminal dispatcher 40 to terminal user interface objects 32.
