URR?
Query
The URR? query reads and clears the contents of the User Request
status Register (URR). The URR register specifies which button
the menu field was pressed. Refer to Table 9 for further details.
In the remote mode, the URR register indicates the last button
(2 ... 10) which was pressed. In local mode, the URR register indi-
cates whether the CALL HOST button has been pressed. If no
menu button has been pressed since the last URR? query, the
value 0 is returned. Figure 1, (page NO TAG) shows the button
assignments on the instrument.
