Response String Structure

Characters in response strings are expressed in a combination of hex and ASCII characters. For clarity,

the following protocol examples use the following conventions:

ASCII characters or strings are shown enclosed in single quotes

Numbers shown that are not in single quotes are a single decimal byte

Parameters shown in < > brackets are single byte

A series of multiple commands or parameters are set apart by [ ] brackets

Commas separate the bytes, but are not part of the protocol

Double quotes enclose the command string, but are not part of the protocol

Command format
