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.
