Procedure to access CLI
This document uses Windows XP operating system; however, you can use any terminal emulator (Serial Communication program) with the operating system present. The COM port properties will remain constant for any third party terminal emulator chosen.

Step 2. Enter the connection name in the Name field.
Step 3. Choose an icon from the given icons in the Icon field.
Step 4. Click OK. The Connect To window opens.
Step 5. Choose COM1 from the drop-down list in the Connect using field. We do not need to configure location details, as we are using COM port.
Step 6. Click OK. The COM1 Properties window opens.
Step 7. Choose the baud rate from the Bits per second drop-down list. The default value is 115200; this can be changed from both the GUI and CLI.

Step 9. Choose None from the drop-down list in the Parity field.
