Introduction

Data Transfer Rates Up to 1 Mbps

Our powerful COMH 232 ISA sync/async adapter can increase your maximum performance by nearly 10 times over async-only cards. This sync/async adapters use DMA (Direct Memory Access) to transfer data at up to 1 Mbps. These boards are based on the Zilog™ 85230 Enhanced SCC chip featuring software-selectable baud rate. They can accept an external clock or provide a clock allowing the application to remain in sync.

Our COMH 4111 includes DMA support, allowing full-duplex DMA transfers on both channels as well as a terminal count interrupt. Connectors are 25-pin male.

Our free Developer's Toolkit™, featuring drivers, samples, applications, and programming information collected over the years, is included. Our goal is to provide the developer with a single high-level programming interface that will function with a wide variety of CyberResearch products across today's mainstream operating systems, including DOS and Windows® 95/98/2000/ME/NT.
