Timing Parameters
The system continuously measures the parameters of the signals. The answer consists of 16 data bytes
and every data byte is represented as a two-digit hexadecimal number. The parameters could be useful for
advanced debugging processes.

The signal type is set to DVI, the other parameters have not been changed. The second, third, and fourth
parameters are 'x' in all cases (because of compatibility reasons). Use the 'x' character to keep the actual
value of a parameter. The response contains the new settings in the
<OUT_SET>
block; see the details in the
Parameters section.
