SGP Adapter
	SGP: Dual or Quad Port PCI Adapter for 5v PCI buses SGP is available as a two or four port high-speed synchronous communications adapter. SGP's design incorporates a Bus Master Controller to transfer data directly from the serial communications line to PC memory, allowing the adapter to support speeds exceeding 4 Mbps with minimal bus and CPU overhead.
	SGP3: Dual Port PCI/PCI-X Adapter for 3.3v PCI buses SGP3 is available as a two port high-speed synchronous communications adapter. As with the SGP, SGP3's design incorporates a Bus Master Controller to transfer data directly from the serial communications line to PC memory, allowing the adapter to support speeds exceeding 4 Mbps with minimal bus and CPU overhead.
The SGP and SGP3 is available with RS-232, V.35, X.21 or RS-422 electrical interfaces in a mix and match manner. No DIP switches and no jumpers are required. Each adapter occupies a memory window that can be mapped anywhere in a bus address space (0-4 Gbytes for PCI). Standard software releases support up to four adapters per machine. On a special-order basis, software drivers are available to handle up to 16 adapters in one system. The Software Group's Wanware and Netcom II software are written specifically for this adapter line (SG2P, SG4P, and SG2P3).
