说明：  VB写的通过串口与考勤机连接通讯的程序,便于工作查看，调试。(VB written through the serial port and Attendance Machine Connection Communication Procedures, easy to see the work, debugging.)

MODBUS通信协议，用VC6.0调试通过，非常好用，做上位机用这个很好(MODBUS communication protocol with VC6.0 debugging through, very easy to do well with this PC)

一个与仪表通讯的上位机程序源码，采采用RS232通讯，协议为MODBUS (A host computer program source code with the instrument of communication, mining RS232 communication protocol MODBUS)

在VC++6.0中用MSComm控件编程，可以实现串口接(used in VC 6.0 MSComm programming, serial port access can be achieved)
