通过手机串口发送短信的VB控件代码,在NOKIA等手机上已经通过测试.

该程序演示了如何在windows平台下使用WindowsAPI函数来操作串口，可以用以实现两台PC机之间的实时聊天。（必须连接串口电缆）-the program demonstrated how the Windows platform using Windows API function to operate serial ports, can be used to achieve between two PC real-time chat. (Must connect serial cable)

串口控制程序一般分为查询和中断两者方式。查询方式适用于简单的应用，简单可靠，但是缺点是需要占用处理器资源，在发送或者接收数据的时候不能做其它的事情，处理器利用率低。中断方式下，在发送或者接受数据的时候处理器还可以做其它的工作，效率较高。-Serial control procedures will generally be divided into two way query and interruption. Query applied to simple applications, simple and reliable, but the drawback is the need to occupy processor resources to send or receive data at the time should not make other things, the processor utilization rate. Interrupt mode, the send or accept data when the processor can do other work, more efficient.
