Introduction
Overview
The Sealevel Systems
232
equips the PC with 1 USB to RS-232 Asynchronous serial port
providing a versatile interface for common RS-232 needs (i.e., modem, mouse, and plotter). The advantage
of this product over more traditional approaches is that it doesn’t require opening the co
mputer 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.
