Wait-to-continue: *WAI
*WAI This pauses until other commands are completed. Two types of device commands exist:
• Sequential commands: A command whose operations are allowed to finish before the next
command is executed.
• Overlapped commands: A command that allows the execution of subsequent commands while
device operations of the overlapped command are still in progress.
The *WAI command is used to suspend the execution of subsequent commands until the device
operations of all previous overlapped commands are finished. The *WAI command is not needed for
sequential commands.
