7.4.4.8 Example of using Double Size Attribute

In parallel mode, Double Size characters can be

obtained as follows. This attribute concerns two

consecutive rows. The character to magnify must

be repeated on the two rows. Bits 2 and 3 of the

shape attribute must be set on the two locations. In

addition bit 4 must be set or reset to define the top

or bottom half-character.

7.4.4.9 Example of using Underline Attribute

In parallel mode, the Underline mode on character

can be obtained simply by setting the bit 1 ‘US’ of

the shape attribute. To underline double height

characters, set the US bit on the attribute associat-

ed with the lower part of the character.

The underline attribute is ignored in the upper half-

character.
