VB6.0环境下直接利用MSComm控件实现分布式下位机群控制

Directly Use MSComm to Implementthe Control of Slave Microcomputers in Visual Basic

VB6.0在环境下直接利用MSComm串行通信控件属性中的奇偶方式位,通过动态改变的值,选()或()或SettingsPPMMarkSSpace者选()或()来模拟串行信息帧中的地址数据使能位,从而实现对分布式下位机群的控制。EEvenOOdd/

In Visual Basic, we can directly use MSComm's settings parity, set the option 'M or S' or 'E or O', by which modulate the address/data enabling bit in serial information frame and implement the control of distributed slave single-chip microcomputers .
