HUAWEI MU509 HSDPA LGA Module
AT Command Interface Specification
All interfaces herein refer to the interfaces between TE and MS, and are used for
guiding the implementation of the function requirements. The interface covers short
message receiving and sending, phone book statistics, and MS network system
information setting.
For the commands sent from TE to MS, see also the detailed description in Appendix
17 . Note that in the returned results of the TEST command, "," and "-" are different.
For example, the returned result of "+CMGD=?" is: +CMGD: (1,5),(0-4), which means
that the first parameter value may be 1 or 5, and the second parameter value may
range from 0 to 4.
