Introduction

Our new USBS 221 converter provides your PC with an asynchronous serial port directly from an existing USB port. It's especially handy for common RS-232 devices such as modems, mice, and plotters. With our USBS 221 you don't have to open the computer case, use scarce COM: ports, or fuss with IRQs. You do need a PC system that supports USB both in terms of hardware and operating system.

Each USBS 221 converter includes a FIFO buffer with 384 bytes in and 128 bytes out. The converter includes a 36" cable and supports Windows® 98SE/2000/XP.
