ASCII Functional Overview

The ASCII protocol permits the PLX3x Gateway to interface any ASCII device to
the many protocols and networks available. ASCII devices include barcode
scanners, weigh scales, many field instruments, printers, and terminals. The
protocol supports one to four serial communication ports that provide
accessibility from one to four independent serial networks.
