Description: 用VC实现PC并行端口数字信息的输入/输出 目前，在实验室和工业应用的各种控制系统中，串口是常用的计算机与外部控制系统之间的数据传输通道。由于串行通信方便易行，所以应用广泛。但是使用串行通信，在实时性、速度、数据量等方面受到限制。而计算机的并行端口传输数据时是一次性传送8个位（一个字节）或更多，由于传输量较大，因此数据的传输速度要比串口快，在许多必须讲究传输速度的控制系统里，用PC并行端口与之连接就是一个很好的解决方案 -With VC realize PC parallel port digital information input/output current, in the laboratory and industrial applications of the various control systems, serial port is commonly used in computer control systems and external data transmission channel between. Due to the convenient option of serial communication lines, so a wide range of applications. However, the use of serial communication, in real-time, speed, data volume, etc. is restricted.
