This escape sequence defines those characters corresponding to ASCII codes
224 (&HEO) to 254 (&HFE). This sequence consists of eleven bytes as follows:
Keyboard Decimal Hexadecimal
Byte 1: ESC 27 lB
Byte 2: GRPH-O 224 EO
Byte 3: Character code
Byte 4: Pattern for dot row 1
Byte 5: Pattern for dot row 2
Byte 6:
Pattern for dot row 3
Byte 7: Pattern for dot row 4
Byte 8:
Pattern for dot row 5
Byte 9: Pattern for dot row 6
Byte 10:
Pattern for dot row 7
Byte 11: Pattern for dot row 8
The pattern making up each dot row is specified as the ASCII code equivalent
of the binary number whose" 1 " bits correspond to dots which are turned on,
and whose "0" bits correspond to dots which are turned off. For example,
specifying 63 (where 63 is the decimal equivalent of 0011111lB) for byte 4 causes
all dots in dot row one to be turned on when the character code specified in
byte 3 is displayed; conversely, specifying 0 (00000000) causes all dots in the
applicable row to be turned off.
A sample definition for character code 230 is shown below:
