串行口测试程序。例如：程序复位后先向串口发送"Hellow Word!",之后每从串口收到一个字符就把它从串口发送出去...

Dos 串口通信例程实现了FiFO ,中断发送中断接受！-Dos serial communication routines to achieve a FiFO, interrupted send interrupt accepted!

三菱PLC与PC通讯程序，只是简单做了试验，结果较好。-Mitsubishi PLC and PC communication program, but simply to do a test with satisfactory results.

这是恒坚电器提供的完整的c++串口编程源代码-Tsunekata appliances provide a complete c serial programming source code

此例为单片机串口的应用!将串口外接一个串入并出的数字芯片,可实现在单片机的串口扩展成并口输出功能!-This case the application for the single-chip serial! Will add a string to the serial port and a digital chip can be realized in the single-chip serial port expansion into a parallel port output function!

我用vb编写modbus协议,拿出来与大家分享一下，厚厚，希望得到大家的指教-Modbus protocol prepared hard to share with you some thick hope to enlighten all

一个关于Com端口调制的程序。包括向Com端口发送数据及从Com端口接受数据两部分。-a Com port on the modulation process. Including Com port and send data from the Com port to accept data in two parts.
