西门子200PLC与上位机通信 delphi开发经典源码-PC 200PLC with Siemens Communications to develop the classic source delphi

从串口读取数据，有两种方法， 1、每接收一个EV_RXCHAR,就用ReadFile读一次，这样我觉得太恐怖了。 2、接收到一个EV_RXCHAR后，等一定数据量的CPU周期(GetTickCount),再一次性读取缓冲区里的数据。这样做，一般情况下不会有问题，但是，如果数据很多，过了“一定数据量的CPU周期”，还没收完数据怎么办？就会少读数据了。 我用三个线程序来完成串口数据的-read data from the serial port, there are two methods, one, each receiving a EV_RXCHAR, on the ReadFile read, I think this vote. 2, received a EV_RXCHAR after a certain volume of data, such as CPU cycles (GetTickCount), and the one-time reader, the data buffer. To do so, under normal circumstances there is no problem, but if many of the data, and after a "certain amount of data the CPU cycles," also confiscated End Data how do? Few will read the data. I used three lines to complete serial data

GSerial是一个DOS下串口通信程序，程序结构较好，能编出用中断方式接收/发送的多串口通信程序（龚建伟曾用它编过7串口通信程序）。Turbo C++ 3.0 Dos或 Win3X/9X/ME/NT/2K的DOS环境下运行-GSerial under DOS is a serial communication program, program structure better, can be compiled out with interrupt receiving/sending of multiple serial communication program (Dan has used its seven series serial communication procedures).
