Converting Binary Code To An Ascii Character - Digital Equipment VT520 Programming Manual

4. Use Table 7–3 to convert each binary number to the equivalent ASCII
character.
Table 7–3 lists the results of steps 3 and 4 for each possible binary value. All
you have to do is find the 6-digit binary number for each sixel bit pattern in
your character design.
Figure 7–4 shows this conversion for the uppercase D in this example.
You use this procedure to convert each character of your soft character set into a
string of sixel bit patterns. Then you can download your DRCS characters into
the terminal, using the DECDLD device control string described in Chapter 5.
