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.
For more information about the READ STATUS command, refer to the
BASEstar Classic Command Line Interface User's Guide

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.
