Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371G)
Commands
The read command returns the current ACM value.
The write command resets the Advice of Charge related to the accumulated call meter
(ACM) value in SIM file EF(ACM). ACM contains the total number of home units for both
the current and preceding calls.
AT+CACM=?
OK
The read command returns the current ACM value. AT+CACM?
+CACM: <acm>
OK
ERROR
+CME ERROR: <err>
AT+CACM=[<passwd>]
OK
ERROR
+CME ERROR: <err>
The execute command can be used to query the current mode of the Advice of Charge
supplementary service, the SIM values of the accumulated call meter (ACM), and the
accumulated call meter maximum (ACMmax).
The write command enables or disables the presentation of unsolicited result codes to
report the call charges.
AT^SACM=?
^SACM:(list of supported <n>s)
OK
AT^SACM.
^SACM: <n>, <acm>, <acmMax>
OK
ERROR
+CME ERROR: <err>
AT^SACM=<n>.
OK
ERROR
+CME ERROR: <err>
