控制短信猫收发短信 (调用WebServices)

需求说明:

  要求定时查询Doing表(待发短信)和短信猫中是否有数据,如果有信息则发送/接收。

表结构

  Doing(ID MOBILID CONTEXT USERNAME DOTIME) --待发送的短信
  Done(ID MOBILID CONTEXT SENDTIME USERNAME )--已发送的短信
  Receive(ID MOBILID CONTEXT RECEIVETIME)--接受道的短信

  GSMMultiPort.dll--控制猫的封装包(为提供)
  里面有:
 ‘初始化’,
 ‘获取短信猫标识号码’,
 ‘获取设备的连接状态’,
 ‘断开连接并释放内存空间’,
 ‘取得错误信息’,
 ‘发送短信息’,
 ‘接收短信息’等方法。
