串口驱动和串口程序。基于RS-232协议的串口通信程序。-Serial port driver and serial procedures. Based on RS-232 serial communication protocol procedures.

用于实现上位机与下位机通信功能。用于串口通信。-For implementation with the lower PC communication function. For serial communication.

要完成串口通信, 在32位模式下, 一般说来有以下四种方法-to complete the serial communications, in 32-bit mode, in general the following four methods :

本文详细地介绍了在Win32环境下通过调用通信API 函数以异步方式来实现PC机和MCS 51 单片机之间的通信过程给出了软硬件设计机理以及详细的通信协议说明-This article described in detail in the Win32 environment by calling the communication API function in order to realize asynchronous approach to PC and MCS 51 Singlechip give the communication process between the design of the mechanism of the hardware and software as well as detailed description of the communication protocol

用vb写的，通过手机模块收发短信的例子程序，串口通讯的-written with Visual Basic, via cell phone text messaging transceiver module procedures example, the serial communications

本软件在C++ Builder 6.0开发环境下编程，实现的功能是：如果将本机的两个串口通讯口COM1和COM2连接起来，可以实现本机内这两个COM口间的数据的传输；若将两台电脑的COM口连接起来，可以实现这两台电脑的串行数据传输。-the software in C Builder 6.0 development environment programming, the functions are : If the machine two serial communication port COM1 and COM2 link up the machine can achieve this within two COM ports of data transmission; if two computers connected to the COM port, This can be achieved two computer serial data transfer.
