How can I use polling with line passing?

With XBee 802.15.4 module and AT mode, I want a base unit to sequencialy poll multiple remotes and each one then respond using the line passing technique for digital status of each DIO. I do not want to use change detection or timed response. Can this be done? If so, what is the AT command to request the response from a remote?

You can do this by sending a remote AT command to perform a force sampling. AT command for this purpose is “IS”

Thanks. I will give it a try.
