Quatech's DSC-100 enhanced serial board provides two RS-232 serial ports on a single PCI board
Expansion card requires no hardware configuration
Computer hardware 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 16550 UARTs with 16-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

There really isn't much to say about a serial card. It was obviously a premium card and it installed and functioned flawlessly. I couldn't have asked for better service from overstock. All in all an excellent internet shopping experience.
