The Serial Data Transfer Interface (SDTI) is a feature of the BIOS. It allows software to transfer large amounts of data between objects. The Mark 1 uses the SDTI to communicate with external storage media, local area networks, and various peripherals. The SDTI is used to avoid length limits on native LSL communication functions such as llRegionSayTo.
