Command Structure:
Each command starts with a # sign (ASCII 0x23) followed by a 3-character command code.
If there are any parameters for the command, the parameters are given in text format, separated by a
space (ASCII 0x20) from the command code.
The # character must never appear in the parameters.
A carriage return (ASCII 0x0d) indicates the end of the command.
A line feed (ASCII 0x0a) can optionally follow the carriage return and will be ignored.
Each command generally may not exceed 20 bytes including the start of command and end of
command bytes.
The illustration of the command structure is as follows:
<Command> = <Start of Command><Command Code>[<sp><Parameters>]<End of Command>
<Start of Command> = #, ASCII 0x23
<Command Code> = <byte><byte><byte>
<sp> = space, ASCII 0x20
<Parameters> = command-specific
<End of Command> = CR, ASCII 0x0d LF, ASCII 0x0a
