User character definition (03) <EXT>

	03	nn
Purpose:
		Defines a custom character.
		Logic Controls Emulation Mode
		The byte that follows the command byte contains an ASCII
		character between X'20' and X'7F' of a keyboard key to be
		redefined. This byte is followed by five bytes defining the bit
		patterns of the user-defined character. Logic Controls Emulation
		Mode allows only one keyboard key to be redefined. This means
		that there is only one user-definable character in this mode. Once a
		key is redefined, any occurrence of that character on the display
		will change to the user-defined character. If a new key is redefined,
		the previously redefined key is restored to the original character in
		all places on the display and the newly redefined key is changed to
		the user-definable character. Table A-1 on page A-3shows the
		format of these five bytes.
		Note: A hyphen character in the table indicates a do-not-care bit.
		The other values relate to the character pixel positions
		shown in the diagram following the table. A value of 1 in the
		data stream indicates that the related pixel position is ON; a
		0 indicates that it is OFF.
