Hexadecimal | 1B 26 s c1 c2 n1 d1 ... | nn dn] |
Decimal | 27 38 s c1 c2 n1 d1 ... | nn dn] |
Values and Ranges
s = 3, the number of bytes (vertically) in the character cell
c = the ASCII codes of the first (c1) and last (c2) characters respectively
c1 = Hex
To define only one character, use the same code for both c1 and c2
n = the number of dot columns for the nth character as specified by n1 ... nn
n=
d = the column data for the nth character as specified by d1 ... dn
The number of bytes for a character cell is s x n1
The bytes are printed down and across each cell
See the illustration.
