3.4. Description of the registers
On switching on the product works according to the last saved configuration (Factory Configuration if it is the first start, or if this configuration
has not been changed). Commands such as Modification TTY<n>=<M> or ATR allow you to change the content of the registers: <n> repre-
senting the number of the register and <m> the value to be assigned. This latter is either a decimal value or a hexadecimal value consistent
with the «encoding» column of the tables below.
Examples:
• ATS300=6 assigns the decimal value 6 in register 300
• ATS320=2 assigns the hexadecimal value 0x02 in register 320
It is imperative to save the parameters with the command AT&W before exiting the Command mode otherwise all changes will be lost.
IMPORTANT: The registers that are not documented (that can appear in the list following the AT/S command) in the paragraphs that follow are
reserved and must not be changed.
