Com Port Connection

1. Device Recognition:

   - Can you see the COM port device in Windows Device Manager?

     - If not:

       - Unplug and re-plug the device.

       - Try reinstalling the driver.

       - Check that the device power LED is on.

2. Testing COM Port:

   - Use the command:

     Echo SomeData >> COM[Number]

     (Replace `[Number]` with the actual COM port number.)

   - This command will show whether the COM port can be accessed, and data can be sent.

If data is sent successfully, you will see a flash on the TX LED of the COM port device and no error Message in the command prompt. you will also get a RX flash on the controller

If you receive a message back it could say access denied or system cannot find the file specified:

This would mean the com port is not accessible, Check you have the correct com port number. try changing the com port number in-case of conflict.
