CL API Terminal App

Overview

As part of the CL API release there is a terminal application included under ./bin, called cl_client (or cl_client.exe on Windows). It is provided as an easy way to interact with devices without having to build your own code.

Terminal application

The terminal application supports both interactive and scripted usage from the command line. For more information, refer to the built in help text by running ./cl_client help.

Example usage for non-interactive mode:

$ ./cl_client list-devices

$ ./cl_client device get-info 10034
