Introduction

Overview

The Sealevel Systems SeaLINK+4/232 equips the PC with 4 USB to RS-232 Asynchronous serial ports providing a
versatile interface for common serial needs. The advantage of this product over more traditional approaches is that it
does not require opening the computer case, nor does it require resources such as I/O ports or IRQs. It does require
a system that supports USB both in terms of hardware and operating system.
