Graphics
The terminal's configuration defines the terminating character sent following the status block
(CR, CR-LF, or RS). Graphics status requests turn on an echo suppress mode in the terminal
(only if the graphics option is installed). This prevents information echoed back from the
computer from being displayed on the screen. Once a graphics status block has been sent,
characters received by the terminal are not displayed until one of the following control
characters is received: BELL, BS, CR, EC, GS,
HT,
LF , RS, US,
VT.
With the exception ofCR and
LF, the terminating control code itself is executed.
The terminal expects the status information to be echoed and uses the terminating control
character to turn off the suppress echo mode. If the computer does not echo the status, a
suitable control character must be returned to the terminal to turn off echo suppression.
The graphics status blocks are shown in Table D-15.
