SST-4P and SST-8P PCI adapters are intelligent, high-speed (up to 920k bps on each port) PCI expansion boards, which provide high performance serial I/O solutions for a PCI bus host computer. All port interfaces are standard RS-232, with full modem control and voltage surge protection on every pin. SST PCI adapters appear to the system host processor as memory.
That is, they are memory<br>mapped devices. Each adapter is automatically mapped into system memory at the time of device driver installation. SST adapters occupy a PCI slot in the host computer and provide the intelligent<br>functions to "off-load" the CPU from serial communications processing tasks.
