FUNCTNS
Pressing this key alternately enables and disables display functions mode. When enabled, an
asterisk appears in the associated screen label. You use display functions mode for entering ASCII
control characters in the
F ldS"p"r" t or
and
Bl kTermn" t or
fields. Note that this implementation of
display functions mode is separate from that which is enabled/disabled via the mode selection keys.
Enabling or disabling display functions mode using this function key does NOT alter the effect of
the
"DISPLAY FUNCTNS"
mode selection key (and vice versa) .

PROGRAMMATIC CONFIGURATION

config
You can change some of the parameter settings in the
terminal configuration menu programmatically by using
escape sequences. Normally these escape sequences are
issued from a program executing in a host computer but
they may also be entered through the keyboard.
Lock/Unlock Configuration Menus
U sing an escape sequence, you can "lock" the current
configuration menus (terminal config, port 1 config, and
port 2 config) so that the menu can neither be accessed from
the keyboard nor altered programmatically. Any attempt
to access a locked menu from the keyboard will result in the
"FUNCTI ON LOCKED"
error message; the terminal operator
clears the message by pressing
l1li.
Note that when the
configuration menus are locked, the
"MODI FY ALL"
(m),
"BLOCK MODE" ( . . ), "REMOTE MODE" (D),
and
"AUTO LF"
(1IlII)
mode selection keys are also locked.
To lock the menus, use the following escape sequence:
<ESC>&g 1 L
To unlock the menus, use the following escape sequence:
<ESC>&g OL
Terminal Configuration Menu
To set the terminal configuration parameters pro-
grammatically, you must use an
<ESC>&k, <ESC>&!!,
or
<ESC»
sequence, depending upon which parameters you
wish to set.

The
<ESC> & k, <ESC>&!I,
and
<ESC»
sequences alter the
particular parameter in the menu, and the new setting
takes effect immediately, but they do NOT alter the con-
tent of non-volatile memory.
If
a configuration menu is
displayed on the screen when the escape sequence is
received, the sequence is executed after the menu has been
removed (by the operator) from the screen.
