3.2.2 Read Status Function

The read status function issues a diagnostic status request to the device, interprets the device response, and returns the response as a character buffer. If a device definition does not match the device in the device response, an error message is displayed and the device definition must be corrected before you can perform an upload function or download function.

Table 3-6 shows how to access the read status function through the BASEstar Classic interfaces.

The read status function allows you to verify if the BASEstar Classic device definition MODEL attribute is compatible with the corresponding physical device. If the BASEstar Classic definition is not compatible, the read status function displays an informational message stating what the actual device is and what it was defined as in BASEstar Classic.
