To enable and disable the security field enhancement, use the character
tt s "
or
tts" as
an <enhancement code>. For example, consider the following escape sequences:
Ec&dsB
Ec&dS
Enable both the security field and inverse video display enhancements (and
disable any other existing enhancements at the current cursor position).
Enable the security field enhancement by itself (and disable any other exist-
ing enhancement at the current cursor position).
Note that
~ts"
or
~~S"
can be used in conjunction with other enhancement codes, but it must
precede the other enhancement.
