 ## Module Description
-Consumer Electronics Control (`CEC`) is a one-wire bidirectional bus within an HDMI system that enables interconnected products to communicate with each other. This module outlines a set of `HAL` `APIs` designed to support `HDMI` `CEC` functionality. The current document details the L3 test definitions and descriptions used to validate these `HDMI` `CEC` `APIs`, including the prerequisites that must be managed before testing and the external stimuli that need to be applied during the test.

 ### HDMI-CEC L3 Test Functionality
 The below pic depicts the HDMI CEC L3 Test Functionality Setup.  TV 2 marked as `DUT` is the Sink device under test.
 
-Note: All the devices used in the test setup should support `HDMI` `CEC` feature during the entire duration of the test.

+### Pulse-8 CEC Adaptor tool:
+The Pulse-8 CEC Adapter will be utilized to frame and send commands to the DUT. This tool leverages libcec, which can be installed to facilitate CEC activities during testing. The cec-client tool will be employed extensively throughout the test. Additionally, RAFT can use this tool to automate the test cases.

+**Commands used during the test:**
+To get the COM port of the `CEC` Tool adaptor: cec-client -l
+To find the devices connected (with their logical and physical address): echo scan | cec-client <Port> -s -d 1
+To Tx and Broadcast: echo tx <frames> | cec-client <Port> -s -d 1
