Abstract: A communication system for providing a communication path between two of a plurality of devices. A first port 30 is connected to one device and a second port 32 is connected to a second device. A switch 40 connects the two ports for communications connection between the ports in response to commands from the devices to each other. The switch includes the capability of monitoring communications between the devices and determining when a change is to be made in the communications path and then making the change accordingly.

Abstract: A display control means such as a virtual display adapter (110) allows the advanced functions of a display controller to be utilized in a large area of memory in addition to the normal use in display memory (120). This large area of memory includes system memory (130), and efficient access to this large area of memory is permitted for normal system use. The display controller also functions with non-contiguous and non-resident bitmaps. The flexibility of demand-paged virtual memory is utilized for display tasks, as display bitmaps may be written to the large area of memory as well as the display memory.
