3.5.4.2.4 Service Reporting Control - +CR
+CR - Service Reporting Control SELINT 0 / 1 / 2
AT+CR=[<mode>] Set command controls whether or not intermediate result code +CR is
returned from TA to TE.
Parameter:
<mode>
0 - disables +CR reporting (factory default)
1 - enables +CR reporting: the intermediate result code is transmitted at
the point during connect negotiation at which the TA has determined
which speed and quality of service will be used, before any error control
or data compression reports are transmitted, and before the intermediate
result code CONNECT is transmitted. Its format is:
+CR: <serv>
where:
<serv>
ASYNC - asynchronous transparent
SYNC - synchronous transparent
REL ASYNC - asynchronous non-transparent
REL SYNC - synchronous non-transparent.
Note: this command replaces V.25ter [14] command Modulation Reporting
Control (+MR), which is not appropriate for use with a GSM terminal.
