LayGO PXS User's Guide - Configuring synctunnel

The Synchronous Tunnel Server application is synctunnel. It should be loaded in the PXS flash memory and defined as default application. See "Updating Software" in the LayGO PXS Installation Guide manual if you need to download synctunnel to the PXS and use the RedBoot default command, if necessary.

The configuration of the Synchronous Tunnel Server relies on LayGO .cfg files stored in Flash memory, which can be specified for each line in the application options parameter of the PXS, using the RedBoot options command. LayGO .cfg file contains all the configuration options related to X.21 bis. See LayGO Configuration for details.
