The ESC 247 code allows the programmer to switch the various shift keys on
and off. Thus the numeric key pad can be set on, or the shift key 'held down'.
The key state is set to normal by the user pressing the appropriate key, so it
is advisable to program with the possiblity in mind that the key may be reset
outside program control.
The sequence of characters is as follows:
