Using the debug port on M95

In the hardware design guide for M95 there is a reference to a document named:
Document[7] : GSM_Multi_UART_Application_Note
I can not find this apllication note

Where can find it?

I would like to use the debug to see if there is anything wrong with the modem

Do you have other guides on how to enable and use the debug port?
