Suppose you want to define the F20 key to be PRINT with-
out clearing or locking any other keys. The first part of the
sequence would look like this:
DCS 1 ; 1 | 3 4 /
where 34 is the code for the F20 key.
After the slash character (2F hexadecimal) you would
include the definition. The rest of the sequence after the
slash character would be,
5 0 5 2 4 9 4 E 5 4 ST
where the hex encoding for PRINT is:
50 = P
52 = R
49 = I
4E = N
54 = T
The ST character (9C hexadecimal) marks the end of the
control string. The complete string is:
DCS 1 ; 1 | 34 / 50 52 49 4E 54 ST
Down-Line Loadable Character Set
The wireless station does not support the ability to create
and down-line load a character set of up to 94 characters
(Table 8-26). This character set is also called a dynamically
redefinable character set (DRCS).
