:WAIT
queries received through GPIB until after the IBASIC program exits the RUN
state; that is, the program is either PAUSED or STOPPED.
CAUTION:
The Test Set will continue to process GPIB commands into the GPIB input buffer
up to the point that the buffer is full. If the external controller attempts to send
more commands than can fit into the GPIB input buffer before the IBASIC
program is PAUSED or STOPPED, the GPIB bus will appear to be locked up. This
is due to the fact that the GPIB bus and the external controller will be in a
temporary holdoff state while waiting for the GPIB input buffer to empty.
If a query command is sent to the Test Set while the IBASIC program is under the
influence of a :WAIT command, no data will be put into the Test Set's Output
Queue until the IBASIC program is either PAUSED or STOPPED. If the external
controller attempts to enter the queried data before the IBASIC program is
PAUSED or STOPPED, the GPIB bus will appear to be locked up. This is due to
the fact that the GPIB bus and the external controller will be in a temporary
holdoff state while waiting for the data to be put into the Output queue to satisfy
the enter command.
