该资源可实现Tq2440与51单片机串口通信，2440向51发送信息，51收到后将收到的消息回传给2440，并在2440上显示出来，2440上程序用qt开发，2440上串口选择tq2440_serial1(也就是com1，linux下叫ttyS1，因为0口被天嵌用作调式口)，用杜邦线分别接2440的TXD1、RXD1和51的Rxd、Txd相连。-This resource can be realized Tq2440 with 51 single-chip serial communicatio

linux环境下，在qt平台编写开发的串口通信例程-a serial port communication programm in qt environment

针对TQ2440开发板上的Keil编程，是从ADS移植到Keil中去，主要实现的是开发板和电脑之间的串口通信。 -Keil TQ2440 development board for programming, is transplanted to Keil from ADS to go, the main achievement is the development board and the serial communication between computers.
