1.3 Interface Change Principles
For the extended interface, parameters can be added behind the AT command. If the
interface fails to meet the new requirements as detected in the later stage of product
development, new parameters can be added on the basis of the original interface. In
addition, for all the currently available interfaces, if the command received by MS is
not identifiable, the "result code" of COMMAND NOT SUPPORT will be reported; if
there is one surplus command parameter, the MS will report the "result code" of the
corresponding TOO MANY PARAMETERS. No equal mark itself is deemed a surplus
command parameter.
All newly added AT command interfaces of the E630 project team begin with "%". This
project team specifies that: In the AT command name such as "AT%XXX", the number
of X cannot be more than 9 currently.
Issue 18 (2009-06-22)
uploads the carriage return character (<CR>) and linefeed character (<LF>) in
the string in the form of space.
A sort of compounding between quotation and comma can not exist in the string
in this current version. For the data format of UCS2 code, the code value should
be reported in the string format (if the code value is 0x553a, 553a should be
reported).
The "Possible response" sent from MS to TE is composed of "Information text" and
"Result code", where "Information text" is optional, and "Result code" is mandatory.
The format of "Possible response" is controlled by the ATV command, as detailed in
the ATV command description. All "Possible responses" listed in the tables in this
documents are in the ATV1 format.
PCUI means module initializes successfully, could deal with AT command
normally.
