58 E1442A Command Reference Chapter 3
DISPlay
The DISPlay subsystem monitors the channel state of a selected module
(or card) in a switchbox. The DISPlay command subsystem only
operates with an RS-232 terminal connected to the E1406 Command
Module’s RS-232 port. These commands control the display on the
terminal, and would in most cases be typed directly from the terminal
keyboard.
However, it is possible to send these commands over the GPIB interface
and control the terminal’s display. In this case, care must be taken that
the instrument receiving the DISPlay command is the same one that is
currently selected on the terminal. Otherwise, the GPIB command will
have no visible effect.
