Caps Lock Mode; Format Mode - HP 262SA Reference Manual

Terminal Control
Caps Lock Mode
When Caps Lock mode is enabled, the terminal generates only Teletype compatible codes:
uppercase ASCII (OO-5F, hex) and DEL (7F, hex). Unshifted alphabetic keys (a-z) generate
the codes for their uppercase equivalents, the {,
I,
and} keys generate the codes for [, \, and]
(respectively), and the' and ~ keys are ignored.
From the keyboard, you enable and disable Caps Lock mode using the
Cap s Loc k
field of the
Terminal Configuration menu described in Section 3.
From a program executing in a host computer, you enable and disable Caps Lock mode using
the following escape sequences:
ENABLE:
Ec
&
k 1C
DISABLE:
Ec &kOC
At any given time the current state (enabled/disabled) of Caps Lock mode is reflected in the
Caps Loc k
field of the terminal configuration menu. When you enable or disable the mode by
altering the menu field from the keyboard and then pressing the
SAVE CONF I G
key, you alter
both the active and non-volatile memory versions of that field. When you enable or disable
the mode using the escape sequence, however, you only change the active value of the
Caps Lock
field in the terminal configuration menu.
After a hard reset or turning off the power, the terminal reverts to the mode specified by the
Caps Lock
field in the terminal configuration menu in non-volatile memory.
Format Mode
The terminal includes a Format mode in which elaborate, custom-designed forms containing
protected and unprotected fields can be displayed on the screen and used for data entry.
When Format mode is enabled, the terminal operator may only enter data into unprotected
fields. If the operator positions the cursor in a protected area and then attempts to type data,
the cursor automatically moves to the start of the next subsequent unprotected fIeld before
the terminal accepts the data.
From the keyboard, you enable and disable Format mode using the
FORMAT MODE
function
key, which is available in the Define Fields set of function keys.
From a program executing in a host computer, you enable and disable Format mode using the
following escape sequences:
ENABLE:
Ec W
DISABLE:
Ec X
Once Format mode is enabled, it remains enabled until explicitly disabled, until a hard reset
is performed, or until the power is turned off
