The Local Listener is automatically activated (on HTTP port 5080) the first time the Cleo Harmony, Cleo VLTrader, or Cleo LexiCom application is launched. This makes web browser service (supported only on Unix and Windows platforms) available out-of-the-box for systems lacking a graphics console. All other services require further user configuration before they are ready and available.
The Local Listener runs with the default, minimal configuration. You can change and save configuration as needed for the AS2 service or other services while the Local Listener is still running and it will remain running as long as it is listening on at least one port. If you save invalid or incomplete configuration changes, the Local Listener will fail to run the next time it is restarted.
