6. A message slated for Any Line is displayed on the same line that

it was displayed on by the Master Device. If the message was a
Hidden Any Line message, it is displayed on line 1 of the slave’s
display.

7. A message with address 127 is placed in a buffer and is sent to all

slaves. All other buffers with the same Line Number attribute
(e.g., Line 3) are cleared.

8. A message with address 127 slated as an All Lines message is

placed in a buffer and is sent to all slaves. All other buffers are
cleared.

Note: If the terminal operator accesses its Front Panel Editor, or
switches the RS-232 port to MessageBuilder parameters, all slaving
activities are interrupted. Slaving activities are resumed when the
operator sets the RS-232 port to Aux. Port parameters and exits the
Front Panel Editor.

Slave Message embedded variables

Numeric and ASCII Entry variables and Function keys are supported
in slaved messages, but they are active only on the Master Device.
The terminal removes the embedded entry variables, enabled
Function keys and (unless Ctrl-G is used) embedded Graphic
symbols before transmitting the message to the Slave Device(s).

If the following are embedded in messages, they are supported on
both the Master and the Slave Device(s):

date and time

graphics (if Ctrl-G is used; see Page 7–41)

Numeric and ASCII Display variables

Data variables are continuously updated in the slave display as long
as the slave message is active.

Other features include:

Numeric Display variable data may be scaled.

Messages with the Hidden and Slave Enable attributes set are not
displayed by the master, but are displayed by the slave device
