Code Dump Header
The "Code Dump" header is identical to
the "Diagnostic" self-test header, except
for the test identification in the first line.
Following the header, the received data is
printed in a structured field dump format
(See Figure 4 ). This shows the data as
received from the host system with each
SCS command on a separate line. Data is
presented in a standard Hex Dump format.
