+CR=<n>
+CR?
Note: This command
replaces the V.25ter
command Modulation
Reporting Control +MR,
which is not appropriate
for use on the GSM
network.
Service reporting control
Sets whether service type is returned (using the result code +CR: <service>)
when the modem has determined which speed and quality of service will be
used, but before any error control or data compression reports are transmitted,
and before CONNECT is returned.
• <n>=0 sets the modem not to report the service type.
• <n>=1 reports service type.
+CR? returns the current setting.
The <service> parameter in result codes reports:
• ASYNC asynchronous transparent
• SYNC synchronous transparent
• REL ASYNC asynchronous non-transparent
• REL SYNC synchronous non-transparent
Data compression reporting can be enabled with the +DR command (page 96).
+CRC=<n>
+CRC?
Cellular result codes for incoming calls
Sets whether incoming calls or GPRS network requests for PDP context
activation indicate a simple RING or a detailed, extended-format result code in
the form +CRING: <type>:
• <n>=0 disables the extended format, returning only RING.
• <n>=1 enables the extended format in the form +CRING: <type>.
+CRC? returns the current setting.
Supported values
Incoming calls or PDP context activation requests report the following values for
+CRING: <type>:
<type>=ASYNC asynchronous transparent
<type>=SYNC synchronous transparent
<type>=REL ASYNC asynchronous non-transparent
<type>=REL SYNC synchronous non-transparent
<type>=VOICE normal voice
For GPRS context activation, <PDP_type> and <PDP_addr> are as defined in
the Define PDP Context (+CGDCONT) command (see page 65).
