Terminal Line Adjustment
The printout of the command response can be adjusted to the screen size
of the used terminal. This feature stops the printout every time the
terminal screen is full. This is especially useful with the small screens of
palmtops. Without this feature the user will only see the bottom lines of
the long command responses such as the STATUS message.
The terminal size adjustment is done using the following command:
SET TERMINAL_LINES number
The standard PC terminal program has 24 visible lines. This is also the
default value for the parameter. The minimum number of lines is 5. This
parameter has no effect on the message sending when the commands are
given in the command polling format.
Command Polling
All commands can also be executed without opening the command line.
This feature can be used in the host system, for example, for making
automatic status message inquiries of active warnings or alarms.
The general command polling format (with 1 as the unit ID) is the
following:
!LT1"&DO_COMMAND-#CSUM$-*
