金卡（gold card),俗称84卡，即采用pic16c84芯片的智能卡，读写编程程序。用vb4写的。-gold card (gold card), commonly known as 84 cards, the chips used pic16c84 smart card reader programming procedures. With vb4 writes.

用C51编写的基于51单片机串口点对点双向通信程序，特点是具有可靠的通信失败检测及信息重发功能。-with C51 prepared by the 51 microcontroller-based point-to-point two-way serial communication program, which is characterized with reliable communication failure detection and re-issued the information function.

PLC串口编程,通过RS232和RS485与上位机通讯.-PLC serial port programming, through the RS232 and RS485 communication with the host computer.

串行数据标准选用之我见 RS-232、RS-422与RS-485标准及应用 转换器的构成 -Selection of serial data standards, I see the RS-232, RS-422 and RS-485 standards and the application of the composition of converter

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

这是一个红外温度探头测试程序，用于对温度探头进行测试，同时也可以作为温度采集用。由于探头通过RS232与计算机连接，所以程序包括串口通信的实现，串口通信利用了第三方通信类CSerial。程序可以将测得的数据保存为Excel文档。-This is an infrared temperature probe testing procedures used to test the temperature probe, but also used as temperature acquisition. As the probe through RS232 connection with the computer, including procedures for the realization of serial communications, serial communications using a third-party communications category CSerial. Procedures can be measured data to Excel document preservation.

实现串口的数据收发，设置串口的打开，波特率设置，收发进制转换-Serial data transceiver, set to open the serial port, baud rate settings, send and receive hexadecimal conversion

一个手机串口通信的类子，值得参考！！！如果你刚学习串口通信，一定值得下载！ -A mobile phone sub-type of serial communication, it is also useful! ! ! If you are just learning of serial communication, it is worth to download!

232通讯 用于电脑232通讯 可以发送和接受数据-232通讯

详细介绍了使用VB开发RS-232通信程序的全过程，并介绍了vb通信控件的用法。-Described in detail the use of VB-RS-232 communication program the whole process and introduced the use of the Communication Control in vb.
