This unit
The Comtrol 99344-5 RocketPort uPCI Octa DB25 is a serial port expansion card that adds eight RS-232 serial ports to a computer system through a single Universal PCI slot. Built around a dedicated 36 MHz RISC processor, this card minimizes host CPU utilization while delivering reliable data transmission up to 460.8 kbps. The card supports 32-bit and 64-bit PCI architectures operating at 3.3V or 5.0V, with no interrupt assignment required - simplifying installation and eliminating conflicts.
