Hi,
I think you might need to disable the TTY console.
This is done via a config text file in the boot sector.
I'm not in a position to check or give further details just at the moment.

Yes, just to confirm, you need to
Disable the (serial) Console
Enable the Serial Port
This can be done from the "Raspberry Pi Configuration" app

Good day LeighM

Thank you very much its working now

Summery for some one that mite be reading this in the future

Step 1 make sure you have the latest operating system on the pi this makes the rest much easier
step 2 enter the GUI and disable the serial console or config file
step 3 enable the serial port
step 4 save and reboot

In my case i still had an old operating system running on it and on the old systems it require dive in to the text files and still had issues until
I loaded the latest operating system
