摘　　要：简述了ＰＣ机ＲＳ－２３２Ｃ串行接口的通讯机理，讨论了Ｗｉｎｄｏｗｓ３Ｘ及Ｗｉｎｄｏｗｓ９５平台实现三线制串行通讯的方法和技巧，利用ＤＥＬＰＨＩ语言提供的嵌入汇编功能，给出了用ＤＥＬＰＨＩ语言实现Ｗｉｎｄｏｗｓ３Ｘ平台下实现三线制串行通讯的过程和函数，详细描述了Ｗｉｎｄｏｗｓ９５把串行口当作设备文件的操作方法。In this paper,the author discusses the principle of serial communication of RS-232C in PC. The general principle of serial communication making use of three line system on DELPHI under the Windows3X and Windows95 is introduced. The function of assembly language inserting in DELPHI language is made used and the communication control method and procedure and function based on DELPHI for serial communication are analyzed in detail. This paper describes, in detail,the operating method of using serial port as files.
