I - Changes
===========

* 01/11/06  -   V1.00
  Initial revision.

* 02/04/22  -   V1.10
  New Wavecom sample library.
  The "AT+WOCM=1" command is now always available.



II - Application description
============================

 This application provides unsolicited responses in order to inform the
external application of the current call operations. The syntax of this
unsolicited response is the following (Wavecom OpenAT Call Monitor) :

  +WOCM: <ID>,<dir>,<status>,<mode>,<mpty>,<number>,<type>,<alpha>,<exit_cause>

 All parameters are similar to the +CLCC response, except the <exit_cause>
parameter. This one is equal to 0, except when the call is released : this
parameter is then the error returned by the +CEER command. A new +WOCM
unsolicited response is displayed when the <status> parameter has changed for
this call <ID>. In addition with the +CLCC <status> values, the status value
takes the value "6" when the call is released.



 A log system is provided to save in Flash Memory the last unsolicited +WOCM
responses for each call ID. This system is managed by the +WOCM command :

        (Test Command)
        AT+WOCM=?
        +WOCM: (0-3),(1-7)
        OK

        (Read Command)
        AT+WOCM?
        +WOCM: <mode>,<logs>
        OK

            <mode> : 0 or 1, shows if the log saving system is enabled or not
                     (disabled by default)

            <logs> : hexadecimal string, each bit (from 0 to 6, for each call
                     ID) is set if a call log was saved for this call ID. 
                     "01" : a log is saved in Flash Memory for call ID 1
                     "0A" : a log is saved in Flash Memory for call IDs 2 and 4

        (Parameters Command)
        AT+WOCM=<mode>[,<ID>]
        OK ot +CME ERROR: 3

            <mode> : 0     to disable the log saving system (default) ; <ID>
                           param is not used
                     1     to enable the log saving system ; <ID> param is not
                           used
                     2     to read the saved log of the <ID> parameter
                     3     to delete the saved log of the <ID> parameter

            <ID>   : 1-7   log ID to read or delete, for <mode>s 2 and 3

 This command is only available when the product is in IDLE state, once the PIN
code has been entered.
