1. When an incorrect or undefined command is detected, an ERROR or +CME ERROR result code is sent back. This rule does not apply for the following commands in order to be compatible with most commercial softwares: C, DL, DS, F, L, M, N, P, T, X, Y, &A, &G, &J, &M, &N, &P, &Q, &R, &S, &U.//一般情况下,会返回error或者+cme error. 但是为了兼容,这些at不会返回错误.;

2.When the PIN is not ready, a restricted set of AT commands are available. These commands are: B, D112, E, I, Q, S0, S2, S7, V, Z, \N0, \N4, \V, +CGMI, +CGMM, +CGMR, +CGSN, +CIND, +CPAS, +CPIN, +GMI, +GMM, +GMR, +IPR, &C, &D, &F, &K, &V, &W//PIN码错误的时候,这些命令式可用的.
3.When optional parameters are omitted, the assumed value is zero for simple commands and the previous value for extended commands (AT+…).//可选参数省略时,简单的命令会假定参数值为0. 对于扩展命令,会使用之前的一个值.
4.Some commands that require time to execute may be aborted while in progress. These commands are aborted by transmitting any character. Commands that may be aborted are: A, D, +CAJOIN, +COPS //有些执行需要时间的命令,有可能在执行中可用被取消. 传入任何的字符就可以取消.
