摘要
因ＶＢ没有提供直接的Ｉ／Ｏ操作功能，这为开发与硬件接口设备有关的系统编程带来了难度．通过对ＶＢ开发串行通信的软件编程的探讨，给出了Ｗｉｎｄｏｗｓ环境下利用ＶＢ进行调制解调器的控制程序设计，实现了利用电话线在ＰＣ机控制的专用调制解调器之间远程数据传输通信，并提出了提高数据传输可靠性的方法及软件的实现方法．
VB has not afforded the function to operate the I/O directly, which makes it difficult to program the system interface. This paper introduces the design of software for serial communication using Visual Basic and provides MODEM communication control program in VB on Windows, which makes the PC controlled MODEM communicate with long-distance one specially controlled by the PC. And the paper presentes an implementation method of the software to enhance the reliability of the data transmission.
