Video Attributes This group of escape sequences defines the video attributes for screen
positions, as specified by an attribute character. The attribute character is
an ASCII character in the range of 20H to 3FH, whose binary value
defines a bit pattern for the selected video attributes. The bit
combinations in bits 0 through 4 select video attributes as follows:
For example, the ASCII value for the # character (23H) has a bit pattern
of 00011 in bits 0 through 4. Thus, when the # is used as an attribute
character, it results in selecting the dim intensity and blinking attributes.
Your application program can send the attribute character with an Esc 6
or Esc 7 sequence. See the sections on these escape sequences for a full
description of their operation.
The 6530 uses monochrome and color tables to map the attribute
character to the video attributes available for the particular terminal or
PC.
TS530 terminals can use only the 6530’s monochrome video attributes.
PCs running PC6530 can use monochrome and color video attributes,
depending on the capabilities of the PC’s video hardware. Your
