Abstract
A device access controller residing in a first computer system for transferring virtual inputs and outputs representing operations of the first system between the first system and a second system. The device access controller includes a video controller for performing video display operations, a video memory for storing video data representing operations of the first system, a network controller for transferring information between the first system and the second system, a controller processor, and a device access controller bus interconnecting the video controller, the network controller and the processor. A video interface is connected between the first system bus and the device access controller bus for receiving video information including video data and video write addresses from the first system bus and into the video memory and controller and the controller processor and network controller are responsive to the writing of video data into the video memory for reading the video information including the video data from the video memory and the video data write addresses from the video controller registers and transmitting the video information including the video data and the …
