DISPlay
The DISPlay subsystem monitors the channel state of a selected modu le 
(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.
