1.2 Initialisation-Steps:
The AL7024S can store a set of parameters (please see also command “AT&W” in the
“AT command manual”). The RS232 interface parameters can also be stored. Our
Socket Modems AL7024S are preset to “AT+IPR=115200” baud rate”. You should think
about the initialisation-steps that should be made every time the AL7024S is powered-
up. For details see also chapter 5.2 in the “Developer’s Guide”.
