Menu Items
This field is variable length and is a collection of “C” style zero terminated
strings (maximum 17 strings). The maximum length of each string is 20
characters, not including a Line Feed (0x0A) character that may be in the string.
The last string may not have the Line Feed character.
The first string is a title and should not be considered for selection.
It is expected that the receiver of the notification will display the menu items
and return (in the User Selection Result request) the number of the item the user
selects. The minimum value of the Selection Result should be 1 (the first item,
#0, was a title line only). The maximum value of the Selection Result is based
on the number of items displayed.
Return Value:
None
