ESP-4 MI Serial Hub Installer/User Guide
Appendix C: 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 appendix 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.
espinstall.exe
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 that contains all the
commands to install up to 256 serial ports when you start the program.
espinstall.exe /text < filename >
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
You may also log additional information with the Debug and Windowdebug commands (see
Table C.1).
The ESP hubs do not have to be rebooted for changes to take effect.
Creating installation/update command blocks
Installation or update information for an ESP serial hub is delimited using the terms ESP and END.
The opening delimiter is ESP on a line by itself - this identifies the start of an installation block for
a hub. The next command must be TYPE, which indicates the ESP hub model. You may then
