Data or a message is displayed in a specific area of a display of a
computer or an interactive terminal by using a local access network (LAN)
card having processing resources and connected to a network, and a video
card having a frame buffer. The LAN card takes control of the video card
frame buffer independently of an operating system running into the
computer or interactive terminal. Preferably, the LAN card and video card
are connected to the computer by a PCI bus and the frame buffer of the
video card is controlled by a PCI bus master mode.
