2 ESP Serial Hub Installer/User Guide

For serial port redirection, the ESP hub is configured using the appropriate drivers running on any

Microsoft Windows host, or espdiag and espcfg for OpenServer, UnixWare, Linux, Sun or AIX

systems. Certain configuration values are set during driver installation.

The file-driven ESP-Install program may be used to install, modify and remove Windows drivers

for ESP serial hubs without the need for on-site technical personnel. See ESP-Install Program on

page 61.

All other connection methods do not require the use of drivers.
