串口通信程序，通过汇编语言使用BIOS的。
本串行通信程序利用汇编语言通过BIOS中断调用和DOS功能调用实现PC机双机串行通信。其中，上位机和下位机串行口均为辅串口COM2（口地址为2FXH），对外用9针连接器与令一台PC机连接；BIOS通过“INT 14H”4个中断服务子程序，分别完成串口初始化编程、发送一帧数据、接受一帧数据以及测试通信线状态。本程序分为PC机串口自动测试程序（目的是测试串口好坏）和PC机全双工双机通信程序两个部分。-the serial communications procedures through the use of assembly language BIOS interrupt calls and function calls DOS PC Dual Serial Communication. Among them, PC and the next crew will be supplemented by serial port Serial COM2 (I address 2FXH) external with 9-pin connectors and enable a PC connection; through the BIOS "INT 14H," four interrupt service routines, complete serial port initialization programming, Send a data receiving a data communications test and the state line. The procedures are divided into PC serial automatic test procedure (for the purpose of testing Serial good or bad) and full-duplex PC-machine communication program two parts.

随着Windows98的推出，越来越多的微机用户已习惯于Windows操作系统。不过Windows应用软件的开发对于一般工程技术领域的技术人员来说并非易事，然而使用微软的VisualBasic6.0（简称VB6）来开发这些方面的Windows应用软件就十分方便，编程工作量相对较小，只需进行主要应用功能的编程和少量界面控制的编程。本文介绍利用VB6串行通信编程的方法对采用了RS-232接口的仪器,进行串行通信的计算机测控软件开发和实现仪器功能和指标的验收。-With the launch of Windows 98, more and more computer users are accustomed to Windows. But Windows application software development for the general area of engineering and technology and technical personnel is not easy, but to use Microsoft Visual Basic 6.0 (VB6) to the development of these applications on Windows is very convenient, programming workload is relatively small, only major applications programming a small amount of control and interface programming. This paper describes the use of VB6 serial communication programming method used to the RS-232 devices, serial communication control computer software development and the achievement of equipment functions and targets of acceptance.
