Cport3.0 the best use of examples, these are all I have collected a lot of place...

利用MSComm控件，不依赖太多硬件设备，指利用纯软件方法侦测串口通信参数设置情况-use MSComm control, do not rely on too many hardware devices that use software-only method to detect serial communication parameters settings

Serial port programming for Windows and Linux

对带LED显示的非接触IC卡读写器的控制，寻卡、读取卡片的物理序列号、核对密钥、读卡、写卡，通过LED数码管显示卡号等信息。-With LED display on the non-contact IC card reader control, look for cards, the card reader physical serial number, check the key, card reader, writing cards, through the LED digital display card number and other information.

51单片机作为主站的MODBUS通信协议，可实现读写从站寄存器的值 -51 MCU as the main station MODBUS communication protocol can realize the value of register read and write from the point
