早期开发的MS8051与PC的RS232通讯

PIC模拟异步串行通讯UART。用TMR0实现定时查询。任何带中断的PIC上都可以实现。可用此法扩展多个串口。-PIC simulation asynchronous serial communications UART. Timing TMR0 with inquiries. Any interruption with the PIC are to be attained. This method can be extended serial number.

异步串口通信 VC++ 本文参考MSDN及相关网上文章。 ////////////////////////////////////////////// //MyComm.h 多机控制 异步串口通信 //说不定能有用上的。-asynchronous serial communication VC paper and related reference MSDN online article. //////////////////////////////////////////////// MyComm. h multi-machine control asynchronous serial communication// may also be useful for the latter.

通过rs232，发送一条消息到另一端，可以打开端口，检查打开后才输入消息。

用VC实现的串口调试软件-with VC serial debugging software

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!

一些485通讯芯片的资料。做工控的人一定会用得到。-Some 485 communications chip information. Done IPC person will certainly used receive.

sle4442 ic卡读写程序，能够实现在串口通信的条件下，对ic卡进行读写。-procedures sle4442 ic card reader, can be achieved in the serial communication conditions, for ic card reader.
