Valid answer structure
When a read or write command is valid, the device answers, giving the current register value. The answer
structure is symmetrical to the write or read command.
An answer is made of a group of letters (most often the same as the command) followed by numeric
values separated by comma, and ended with
C
R
L
F
characters. (ASCII 0x0D and 0x0A)

characters.
