Conversational Mode In Conversational mode, characters are sent to the host as you type them. This is useful when applications need to interact with you on a character, word or line-by-line basis. Display memory is treated as one long page consisting of 400 lines, of which 24 lines may be viewed at any one time. Lines above or below those currently displayed may be scrolled into view using cursor or display control keys. Once all the display memory has been used, new data forces all previous lines of data up one line so that the first line is erased, ensuring that the oldest data is erased first. The status line displays CONV when you are in Conversational mode. Block Mode In Block mode, characters are stored in a communications buffer and are not transmitted to the host until the application requests them. The characters are then sent as a block. This enables you to enter a large amount of data and edit it locally before it is transmitted. Block mode has two sub-modes: Block Nonprotect and Block Protect. In Block Nonprotect mode you can enter any type of character at any position on the screen (except on the 25th line). In Block Protect mode the application divides the screen into protected and nonprotected areas called fields. The cursor cannot be moved into protected fields, which may contain prompts or information or be empty. The cursor can only be moved into unprotected fields, which may also define the type of characters that can be entered. In Block mode, display memory is divided into pages, the number of pages being determined by the application. The status line displays BLOCK when you are in Block mode, and PROT when in Block Protect mode. ANSI Mode In ANSI mode, characters are sent to the host as you type them, and standard ANSI (American National Standard Institute) functions are executed. Applications that run on the LXN host system generally recognize and use these functions. The status line displays ANSI when you are in ANSI mode. Keyboard Mapping The following illustrations show where TA6530 keyboard functions are mapped to keys on the 83/84 key AT, 101/102 key Enhanced AT and DEC LK250/450 keyboard layouts. The mapping for other layouts can be displayed by using the Show Map option in the Keyboard Macros dialog box, as described in the Setup Menus chapter. TA6530 Emulation 9-3

Conversational Mode
In Conversational mode, characters are sent to the host as you type them. This is useful
when applications need to interact with you on a character, word or line-by-line basis.
Display memory is treated as one long page consisting of 400 lines, of which 24 lines may
be viewed at any one time. Lines above or below those currently displayed may be
scrolled into view using cursor or display control keys. Once all the display memory has
been used, new data forces all previous lines of data up one line so that the first line is
erased, ensuring that the oldest data is erased first. The status line displays CONV when
you are in Conversational mode.
Block Mode
In Block mode, characters are stored in a communications buffer and are not transmitted
to the host until the application requests them. The characters are then sent as a block. This
enables you to enter a large amount of data and edit it locally before it is transmitted.
Block mode has two sub-modes: Block Nonprotect and Block Protect. In Block Nonpro-
tect mode you can enter any type of character at any position on the screen (except on the
25th line). In Block Protect mode the application divides the screen into protected and
nonprotected areas called fields. The cursor cannot be moved into protected fields, which
may contain prompts or information or be empty. The cursor can only be moved into
unprotected fields, which may also define the type of characters that can be entered.
In Block mode, display memory is divided into pages, the number of pages being deter-
mined by the application.
The status line displays
BLOCK
when you are in Block mode, and
PROT
when in Block
Protect mode.
ANSI Mode
In ANSI mode, characters are sent to the host as you type them, and standard ANSI
(American National Standard Institute) functions are executed. Applications that run on
the LXN host system generally recognize and use these functions.
The status line displays
ANSI
when you are in ANSI mode.
Keyboard Mapping
The following illustrations show where TA6530 keyboard functions are mapped to keys
on the 83/84 key AT, 101/102 key Enhanced AT and DEC LK250/450 keyboard layouts.
The mapping for other layouts can be displayed by using the
Show Map
option in the
Keyboard Macros
dialog box, as described in the
Setup Menus
chapter.
