Response Format The response returned for this command is shown below. This response as-
sumes that the header code in the command block was transmitted and read
normally and that the end code is 00. If the end code is not 00, the error status will
not have been read and the end code will be followed immediately by the FCS. If
the header code in the command block was not recognizable, a header code of
IC will be returned without an end code (see
Section 4-1-2 End Codes for the IC
