ESP-Install Program
The ESP-Install program may be used to install, modify and remove redirected serial ports and ESP
drivers on supported Windows systems. By using a script file, you may streamline the process of
installing multiple hubs. The program uses a series of commands (keywords and keyword/value
pairs) to identify address information, assign logical COM ports to physical ports and specify other
driver-related information.
You may also use this program to remove (uninstall) previously installed drivers for ESP serial
hubs. A hub may be removed in the same script file that installs other ESP hubs. This allows you to
update a driver without having to reboot the ESP hubs.
This chapter describes the available commands and how to use them. It is written for administrators
who are familiar with Windows driver features and terminology.
Running the ESP-Install Program
There are two ways to run the ESP-Install program at the command prompt.
• When you type
espinstall.exe at the command prompt with no parameters, a help screen will
be displayed. You may then enter commands to install one hub at a time.
During this process, you may access help information by entering
espinstall /help. You may
generate a current list of port mappings by entering
espinstall /list.
• To automate the installation process, you may specify a script file by entering
espinstall.exe /
text <filename>
that contains all the commands to install up to 256 serial ports when you start
the program. (If the script file is not located in the same subdirectory as the ESP-Install
program, the <filename> parameter should specify the full pathname of the script file.)
The results of the ESP-Install program commands are written to the files ESPsummary.log (if the
requested operations completed successfully) and ESPinstall.log, which are located in the same
subdirectory as ESPinstall.exe.
• 0 = the command(s) completed successfully
• 2 = the ESP-Install program could not communicate with the ESP hub (check the Ethernet
cable connection)
• 3 = an ESP hub with the specified address is already installed
• 8 = an error occurred
