短信猫的开发

emperordj 2008-12-12 12:24:36

公司买了个短信猫,是北京都信技术公司的,可我从来没弄过这个,一点头绪都没有,购买时配了用C#开发的程序,以及动态链接库,现在情况是这样的:
1.用B/S结构
2.短信猫放在服务器上,客户端可通过服务器端的短信猫来发送和接收短信
3.可以自动发送放在数据库中的短信,设定待发时间,按照时间发送

现在我做的有这些:
1.可以连接到终端,然而断开之后再连接,却连接不上
2.怎么实现让它自动拉取数据库中的数据发送(按事先设定的时间自动发送)

贴出部分代码:

购买时附带的接口函数



Sms_Connection(Com_Port As Integer,Com_BaudRate As Integer, Mobile_Type As String) As Integer

         Sms_Connection函数说明如下：

         功能描述：用于初始化终端与串口的连接

         Com_Port：串口号（0为红外接口，1,2,3,...为串口）

         Com_BaudRate：波特率

         Mobile_Type：返回终端型号

         Sms_Connection：返回值(0：连接终端失败；1：连接终端成功)



Sms_Send(Sms_TelNum As String, Sms_Text As String) As Integer

         Sms_Send函数说明如下：

         功能描述：发送短信

         Sms_TelNum：发送给的终端号码

         Sms_Text：发送的短信内容

         Sms_Send：返回值(0：发送短信失败；1：发送短信成功)



Sms_Disconnection() As Integer

         Sms_Disconnection函数说明如下：

         功能描述：断开终端与串口的连接

dll的调用
