A serial link handler is set with the following default values (factory settings):
Commands always start with AT (which means ATtention) and finish with a <CR> character.
Responses start and end with <CR><LF>, except for the ATV0 DCE response format and the ATQ1 (result code
suppression) commands.
In some cases, such as “AT+CPIN?” or (unsolicited) incoming events, the product does not return the OK string as a
