Details of Command

Command has 2 parts, "Command group: CMD-GP" and
"Parameter: PARAM".
CMD-GP is a byte at the head of a command. PARAM is one
or a number of bytes describing the contents of a command.
The length of PARAM is dependent on CMD-GP.
"[CMD-GP],[PARAM0],[PARAM1],[PARAM2],...,[PARAM
N]\n"
Example: "23,a9,00,00\n"
CMD-GP: "23"
Adjust the word-size parameter of Camera
PARAM: "a9,00,00"
PARAM0:
"a9" Parameter address of Master Black of Camera
PARAM1-2:
"00,00" 2 bytes parameter value of Master Black
(PARAM0)
