Overview

The are some special cases for testing binary data.

•

The ascii format is not good for e.g. a length byte 0x41 displayed as A.

•

Multibyte values are better shown as 1 value.

•

Structured binary e.g. 2 byte length followed by bytes better are shown as it is.

•

Compare 2 binary or 1 binary and a dump.
