ABSTRACT:
A menu bypass system for an IBM 3270 type of display system. An IBM 3270 type display system includes a display terminal, a communications controller and a host computer running a host application which controls the terminal. The host computer and terminal communication use a protocol which allows the host to transmit data to and read data from the terminal at any time. After a transmission from the terminal to the host, the terminal is normally locked from further transmission until the host application responds. The menu bypass system allows transmission of request units generated by attention identifiers. These request units are stored in a queue and transmitted to the host one at a time in response to host commands. For certain host commands, such as erase/write, a previous write transmission from the controller to the terminal is aborted.
