    Chapter 6: Commands 7156 Owner’s Guide While MICR data is still outstanding, an application should use the real time GS ENQ. A response to GS ENQ can still arrive “inside” ASCII MICR data, but it can be recognized and extracted. And although ASCII MICR data cannot be distinguished from responses to ESC u and ESC v, those are all non-real time responses and will arrive in the order in which they were solicited.

None of the parsing examples in the following section take more than 14 bytes (seven words) of NVRAM.
