Chapter 3: AT Commands Reference
June 30, 2008 AT Commands Reference Manual 3 -61
Note: If <ppu> contains a dot, a maximum of three digits may appear after the dot, otherwise
an error is generated. For example, if <ppu>=0.61, the Read command displays 0.610.
<ppu>=1.2345 terminates in an error.
If <ppu> does not contain a dot, the number is divided by 1000. For example, if <ppu>=1,
the Read command displays 0.001.
Due to storage constraints, the <ppu> value is limited to a range of 0 to 4095. Values
beyond this range may result in rounding errors. For example, if <ppu>=4095, the Read
command displays 4.095. However, if <ppu>=4096, the Read command displays 4.090
(the last digit is replaced by 0). If <ppu>=456789, the Read command displays 456.000.
+CR, Service Reporting Control
This command controls whether or not the extended format of an outgoing call is displayed or
not. The +CR indication is sent from the G24 to the terminal whenever a data call is initiated by
the G24.
The following table shows the +CR parameters.
Command Type Syntax Response/Action Remarks
Set +CR=[<mode>] OK The Set command enables/disables the
