Read MoreQuatech's DSC-100 enhanced serial board provides two RS-232 serial ports on a single PCI board. As a PCI device, the DSC-100 requires no hardware configuration. The card is automatically configured by the computer's BIOS or operating system. The two serial ports share a single interrupt line and are addressed in a contiguous block of 16 bytes. A special interrupt status register is provided to manage the shared interrupt. The DSC-100 completely adheres to the PCI 2.1 specification, and all PCI registers are properly implemented, so users can be assured that the DSC-100 will not conflict with other properly implemented PCI devices. The DSC-100 is implemented with two 16750 UARTs containing 64-byte FIFOs. It has a clock multiplying feature allowing the board to achieve data rates as high as 921.6 Kbps. The high clock speeds and deep FIFOs will greatly reduce CPU overhead, making the DSC-100 an ideal choice for heavy multi-tasking environments.
