OK/ERROR/+CMS ERROR

Notes 1) The Mobil Equipment storage "ME" has capacity for 25 short messages

2) The storage "MT" is a combination of "ME" and "SM" storage. If "MT" is

chosen indices < 26 refer to ME" storage while indices 26 or higher are

associated with the "SM" storage

3) Incoming short messages with message class 2 (see GSM 03.38) will be

stored in the "SM" storage only. Therefore, the AT^SMGO:2 indication (see

AT^SMGO command) can occur without a preceding AT^SMGO:1 indication.

一些概念：

MEM1：读取和删除短信所在的内存空间。

MEM2：写入短信和发送短信所在的内存空间。

MEM3：接收到的短信的储存位置。

具体用法：

1、语句：

AT+CPMS=?

作用：

测试命令。用于得到手机所支持的储存位置的列表。在我的SIEMENS M55手机上返回：

AT+CPMS=?

+CPMS: ("MT","SM","ME"),("MT","SM","ME"),("MT","SM","ME")

表示手机支持MT(手机终端),SM(SIM卡),ME(手机设备)

2、语句：

AT+CPMS=”MT”,”ME”,”SIM”

设置MEM1为MT，MEM2为ME，MEM3为SIM

3、语句：

AT+CPMS?

作用：

得到当前的设置。

例如通过第二条语句的设置以后返回：

AT+CPMS?

+CPMS: "MT",7,150,"ME",7,100,"SM",0,50

表示MT里面有7条短信，总共可以储存150条。ME里面有7条，共可以储存150条。SIM卡上可以储存50条。
