of the AT commands most commonly used
in day-to-day operation of the modem.
·Entering Access Codes:
To retrieve the Serial Number of the modem (in hexadecimal forma t):
AT+GSN
†
To perform Over-the-Air Service Provisioning (OTASP):
AT+CDV*22899
†
To change to Offline Digital mode:
AT$KWMODE=1
†
To enter the SPC and unlock the modem for programming:
AT$KWSPC=000000
†
To enter the Mobile Identification Number (MIN):
AT$KWDIR=
<MIN>
†
To enter the Mobile Country Code (MCC):
AT$KWMCC=
<3 digit MCC>
†
To enter the Mobile Network Code (MNC):
AT$KWMNC=
<2 digit MNC>
†
To write configuration changes and reset the modem, type:
AT$KWMODE=2
†
·Communication Parameters:
To check the baud rate:
AT+IPR?
To change the baud rate:
AT+IPR=
<baud rate>
(Valid rates: 300, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200 bps)
To change the flow control:
AT+IFC=2,2
