+CRLP=?
Radio link protocol
When originating non-transparent data calls, the
+CLRP
command sets the
Radio Link Protocol (RLP) parameters.
+CRLP?
returns current settings for each supported RLP <version>, each on a
separate line, with only RLP parameters applicable to the corresponding
<version> on each line returned:
+CRLP: <iws>,<mws>,<T1>,<N2>,<version>,<T4>
+CRLP: <iws>,<mws>,<T1>,<N2>,<version>,<T4> etc.
+CRLP=?
command returns values supported by the modem as a compound
value. The RLP parameter value ranges for each <version> are returned on a
separate line:
+CRLP: supported <iws>s, supported <mws>s, supported <T1>s, supported
<N2>s, <version>, supported <T4>s
+CRLP: supported <iws>s, supported <mws>s, supported <T1>s, supported
<N2>s, <version>, supported <T4>s etc.
Note: See also
+DS
Supported values
<version>
is the RLP version number in integer format, either
0
or
1
. If it is not
present,
<version>=0
is the default.
Versions 0 and 1 share the same parameter set.
+CRLP?
and
+CRLP=?
return
only one line for this set (where
<version>
is not present).
<iws>, <mws>, <T1>
,
and
<N2>
are the IWF-to-MS window size, MS-to-IWF window size,
acknowledgement timer, and retransmission attempts, respectively. All are
integers, and their default values and value ranges depend on the RLP
version—see the standard GSM 04.22[18]). However, versions 0 and 1,
supported here, share the same parameter values:
Param Range Default Description
<iws>
0–255

interworking window size
<mws>

mobile window size
<T1>
