ESC[psm Set Character Attributes
Character attributes are invoked when the escape sequence
ESC[psm is received with a single parameter or a combination of
parameters. The sequences used are the ANSI 3.64 standard se-
quences for SELECT GRAPHIC RENDITION (SGR) commands using the
selective parameters:
0
=
normal
1
=
bold
2
=
bold
4
=
underline
5
=
blink
7
=
reverse video
8
=
blank
Exaaple: The sequence ESC[O;4;5m will clear all the attri-
butes currently on and then set underscore and
blink on.
Character attributes along with characters can be cleared
by using the proper clearing sequences (refer to ESC[psJ and
ESC[psK in this section).
Bold, normal intensity, and blank are mutually exclusive.
If one of these intensity sequences is received, it overrides
the previous intensity state. Blank overrides blink. Blink
causes the character to alternate between bold and normal
intensity.
