mscomm的控件，基于VB，C++ 或API的控件。-MSComm control, based on the VB, C++ or API controls.

本程序调用了微软自带的mscomm控件，实现com口的数据接收，读者可自行添加发送数据功能。内附mscomm.ocx控件及其注册方法，本程序是用的静态链接库，为的是能在没有vc库的机器上也可以运行，所以个头大了点。-Microsoft"s own mscomm controls, I realize com data reception, readers can add their own functions to send data. Enclosing mscomm.ocx control and registration method, the procedure is used in the static link library, for the in the absence of vc for the machine can also run, giving the larger point.

针对fidelix模块的测试软件源代码,通过串口,对fidelix(cdma模块)进行控制和检测.-against fidelix test software module source code, serial, right fidelix (cdma modules) for control and testing.

vc实现的一个串口通讯例子-vc achieve an example of 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.

在VB下对串口COMM控件编程和发机制进行了详细地设计，同时可以为串口调试用，不失为一个好工具。习惯于VB编程的朋友可以CC一下了。-in VB Serial COMM under the control programming and the mechanisms to perform detailed design, while it used to debug serial port, is a good tool. Accustomed VB CC friends out.

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.
