The Sealevel Systems DUOCOM: provides PC systems with two RS-232 Asynchronous links to data collection and other devices. Modems, data entry terminals and plotters are some devices that use RS-232 protocols. The DUOCOM: allows for individually selectable interrupts (2-5, 7, 10-12 and 15). This product provides an excellent means for expanding the number of serial ports in a PC, while eliminating COM3: and COM4: IRQ conflicts under Windows 3.1x/95/98/NT and 2000. We include our Advanced COM drivers for Windows 95/98/ME/NT/2000 and XP providing IRQ sharing, Windows serial diagnostics, and other enhanced features. Our Linux and QNX utilities are also included to simplify installation.
