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 (page 97).
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 61 interworking window size
<mws> 0–255 61 mobile window size
<T1> 0–255 48 acknowledgment timer (10 ms increments)
<N2> 0–255 6 retransmission attempts
+CSAS Save SMS settings
Saves the current SMS settings for +CMGF (page 78), +CNMI (page 82), and
+CSDH (page 93) to non-volatile memory.
Note: For information on restoring these settings to active memory, see +CRES
on page 91.
