-----------------------------------
Specifies shape of insert and overwrite mode cursors.
Return value - None
-----------------------------------

<expC>
        Cursor to change.  "I" for insert cursor or "O" for overwrite cursor.

<expN>
        Cursor shape.  0 for underline, 1 for block and 2 for half size block.

If you omit the optional <expN> but include either "I" or "O" in <expC>,
the insert or overwrite cursor is reset to its default setting.  If you
omit both <expN> and <expC>, both the insert and overwrite cursors are
reset to their default settings.
