ASCII (not decimal) and hexadecimal examples are shown below. The commas in the Hex
example are merely for your ease of reading and are not required in transmission. All strings must
have a space between each number or letter (except two digit numbers). In the Hex examples the
space is already represented with code “20.” The end of each string must have a carriage return
after the last number with no space in-between, this is represented by “” in the ASCII
examples and “0D” in the Hex examples.
