Description
The IBM 3164 operates in its own mode; IBM 3163 compatible (Default
Color) mode or Program Color mode.
The IBM 3164 operates in the IBM 3101 emulation mode.
The display station operates in the echo mode. Data entered from the
keyboard is transmitted to the host computer only; data must be sent
back to the terminal for screen display or other functions. in a
conversational manner.
The display station operates in the character mode. Data entered from
the keyboard is transmitted to the host computer and is also sent back to
the display screen.
The display station operates in the block mode. When a Send key is
pressed or a Read command is received. the specified data area in the
character buffer is sent to the host. This allows the operator to edit the
screen data and perform any changes desired before transmitting it to the
host computer.
This option is used to disable the transparent mode. The transparent
mode provides the programmer with a means of verifying the use of
command codes by enabling the terminal to display all code sequences
as they are entered along with alphanumeric characters. However. it
should be noted that command codes are not executed when the
transparent mode is active.
This mode is activated when'the DLE.STX character sequence is received
from the host or entered from the keyboard. It is deactivated by the
DLE.ETX sequence by the host or the operator.
This option is used to determine the character(s) generated when the
Return key is pressed. When the CR (carriage return) option is selected.
the Return key generates CR. When the CR.LF (Carriage Return.Line
Feed) option is selected. the Return key generates both CR and LF
characters.
If the CR.LF option is selected in character or echo mode when CR is a
line turnaround character. the Return key generates the CR and LF
characters and then line turnaround occurs.
In character mode. if CR has been selected as the line turnaround
character and the CR/CR.LF option is set to CR.LF. pressing the Return
key causes the CR and LF functions to be performed. but only the CR
character is sent to the host.
If this option is on. the Enter key functions as the Return key. If this
option is off. the Enter key functions as the Send key.
This option is for the host system to disable the operator initiated Set
Field Attribute command. When disabled. the operator cannot generate
or modify any field attribute on the screen.
This option is used to enable/disable the automatic CRT saver function.
After 5. 10. or 15 minutes of inactivity (no host or operator input) the
display is automatically disabled and the CRT phosphor is preserved.
although the character buffer contents are held intact. When data from
the host is received or any key is pressed. all CRT contents are again
displayed without loss of data. When enabled. one of the three timers
(5. 10. or 15 minutes) can be selected.
