Abstract: The system employed comprises a central computer (12), a number of unprogrammable video terminals (14) and a programmable workstation emulator (15). The CPU (16) is connected to a workstation controller (18). A synchronous data line controller (20) is used with a remote workstation controller (22) at the end of an SDLC link (24), similar to that (24A) connects another SDLC controller (20A) to the emulator. When another function is requested by the user, the nonprogrammable terminal or programmable workstation sends memorised video information to the central computer including image counter data in cache memory, scaling data and on-screen placement data.

Abstract: A method and apparatus are provided for supporting multiple display sessions through a single address on a non-programmable-terminal (NPT) attached to a host computer by a work station controller (WSC). The WSC enables shared addressing of multiple display sessions on the NPT. The WSC changes focus to a selected one of the multiple display sessions responsive to receiving from the host computer a data stream for a requested display session not having the focus and responsive to receiving a change focus request from the NPT. The NPT may have one display session active for the user interface and a different display session having the focus communicating with the host computer, which is transparent to the user and to the host computer.
