Notes:
This command is not specified in the standard interface protocol but is introduced to
prevent the main menu information from being lost because
SET UP MENU
is sent too
quickly.
If the SIM card does not deliver
SET UP MENU
, then
^CUSATM: ""
will be returned after
the main menu is queried.

empty.
