Chapter 1 – AT Commands for Remote SIM Application Toolkit
Multi-Tech Systems, Inc. SIM Application Toolkit AT Commands (S000391C) 31
Response Parameters
<cmdType> 250 – Command ID. See Table 1.
<commandDetails> This byte is RFU.
<iconId> Unsigned Integer, range 0 – 255.
0 Request number of icons on SIM only. Response
parameters which follow <iconCount> are not listed.
1 - 255 Icon ID.
<iconCount> Displays the total number of icons stored on the SIM.
<clutEntries> Unsigned Integer, range 1 – 256.
Number of byte triplets in <clutData> which may be
referenced from inside the image data array. <clutEntries>
has a value between 1 and 2 ** <BitsPerPoint>.
<BitsPerPoint> Unsigned Integer, range 1 – 8.
Number of bits used to encode references into the color
look-up table, thus defining a raster image point's color.
Supported values are 1 and 2 bits per raster image point.
1 bit per raster point applies to a black/white image with
<clutData> equals “000000FFFFFF”.
<iconWidth> Icon width, displays number of raster points.
<iconHeight> Icon height, displays number of raster points.
<iconDataLength> Number of icon data bytes.
<dataType> Unsigned Integer, range 0-255.
0 CLUT data line tag.
1 Icon data line tag.
2-255 RFU.
<lineNumber> Data line counter.
<dataLen> Number of data bytes following on this line, maximal 200.
<clutData> Binary coded data stream containing one RGB byte triplet
for every color.
The CLUT entries are arranged sequentially. Each CLUT
entry in turn comprises 3 bytes defining one color in the
red-green-blue color space.
A value of 'FF' means maximum intensity; e.g., the
definition 'FF' '00' 00' stands for fully saturated red.
So <clutData> containing “000000FFFFFF” codes a CLUT
for black (all colors off) and white (all colors on).
<iconData> Binary coded data stream containing the icon data,
starting with the highest bit of the first raster point´s color
information.
Unused bits of the last byte are filled with ´1´, if any.
Maximal supported number of coded data bytes is 1024.
