+### Pulse-Eight CEC Adaptor tool:
 The Pulse-Eight 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```
