Pushbutton Select and Control (C6, C7 and FB) Commands

The Pushbutton Select command (FB) is a command that performs a
“push” of the specified pushbutton number, just as if the button had actu-
ally been pressed at the control panel. The Pushbutton commands turn the
designated pushbutton “on” (C6) or “off” (C7). These commands are valid
with all pushbuttons.
