when searching a byte array data type (like MISO, MOSI, and many other analyzer result types) that are displayed in the ASCII display radix, you may see dot characters ('.') in positions where the data isn't a displayable ASCII character. These characters cannot be searched for. Only ASCII characters can be searched. For example, if a cell displays 'ab...yz' you can search for 'a', 'b', 'ab', 'y', 'z', and 'yz' to match it, but you can't search for 'ab...yz' because the dot ('.') characters are unmatchable.
