Abstract
A computer system having integrated remote console functionality. Cycles intended for a video graphics controller are snooped to acquire the video data or control information contained in the cycle. Analysis is performed on the video data to detect sequential or repetitive operations. The video data is encoded into higher level primitives, if possible. The video data and primitives are held in a first-in-first-out (FIFO) memory until the FIFO reaches a critical level, or a staleness timer times out. Special firmware executed in system management mode reads the FIFO and converts the video data and primitives into conventional ASCII text or the required format. The firmware also maintains a copy of the video frame buffer to further encode the video data, if possible. The firmware then transmits the conventional ASCII text via a modem to a user stationed at a remote computer system.
