§
s is the number of bytes in vertical direction. s=3.
§
n is the starting ASCII code of user-defined character.
§
m is the ending ASCII code of user-defined character.
When define only one character, n equal m. The maximum number of user-
defined characters is 96.
§
a is the number of dots in horizontal direction.
§
p is the data of user-defined characters. There are (s x a) bytes in each
character, the total number of user-defined characters is m-n+1.
§
user-defined characters are valid until re-defined, reset or power off.
Format of the user-defined characters is shown as follows:
p1
p2
p4 p7
p5
p3 p6
p3a-2
p3a-1

m for setting bit-map graphics mode; n1 n2 for setting number of dots; [d]k for
setting contents of dots.
m=0, 1, 32, 33. n1 = 0 ~ 255, n2 = 0 ~ 3. d = 0 ~ 255.
k = n1 + 256 x n2, (m=0,1)
k = (n1 + 256 x n2) x 3, (m=32,33)
u
The number of horizontal dots of the graphics is n1 + 256 x n2.
u
If the number of dot is more than one line, the extra portion will be
ignored. (refer to the following table)
u
d is the bit-map data, for 1 of bit means the related dot will be printed and
for 0 of bit means the related dot will not print ( k is the total no. of data)

m is the selected bit-map mode
