3.5.3.2.4. Radio Link Protocol - +CRLP
+CRLP - Radio Link Protocol
AT+CRLP=[<iws>
[,<mws>[,<T1>
[,<N2>[,<ver>]]]]]
Set command sets Radio Link Protocol (RLP) parameters used when non-
transparent data calls are originated
Parameters:
<iws> - IWF window Dimension
1..61 - factory default value is 61
<mws> - MS window Dimension
1..61 - default value is 61
<T1> - acknowledge timer (10 ms units).
39..255 - default value is 78
<N2> - retransmission attempts
1..255 - default value is 6
<ver> - protocol version
0
AT+CRLP?
Read command returns current value of the RLP protocol parameters
AT+CRLP=?
Test command returns supported range of values of the RLP protocol parameters.

3.5.3.2.5. Service Reporting Control - +CR
+CR - Service Reporting Control
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 UMTS terminal.
AT+CR?
Read command returns whether or not intermediate result code +CR is enabled, in
the format:
