除此之外抛出的异常也不够详细,SerialPort的Open方法一开始就有一个Port_already_open端口已打开异常,我那边就没有分的这么细了,只要端口打开失败就返回Port Open Failure,异常分的不够细也是不好的。 除此之外就是SerialPort用了大量的枚举,如StopBits、Handshake、Parity、SerialData、SerialError和SerialPinChange,...

I need to be able to determine if any and how many bytes are available prior to attempting to read data from the serial port. Is this possible?I've opened asynchronous communication in C++ with the serial port as follows:HANDLE mFileHandle = CreateFile("COM1", GENERIC_READ | GENERIC_...
第一次进入这个do_work方法的时候,这几个过程都是跳过的,因为没有建立任何连接,我们接着分析下面的一个Switch case的大循环,由于通信状态state的初始值是我们设置的DISCONNECTED,所以首先会进入这个case,在这个case中第一件事情就是根据CommunicationType来决定 进行Tcp连接还是SerialPort连接,我们分别来看下这两个过程。

COM来源于微软的DOS系统,它是一种设备名称,全称 COMmunication port。八十年代的计算机背面通常有两个串行端口,分别标记为COM1和COM2。该名称被延续到Windows操作系统中,大多数模拟串行端口的驱动程序都会创建一个名称为 “COM”的设备。 LPT是并行端口的设备名称,“Line PrinTer”的缩写。
