serial port- an interface (commonly used for modems and mice and some printers) that transmits data a bit at a time interface,port- (computer science) computer circuit consisting of the hardware and associated circuitry that links one device with another (especially a computer and a hard disk...
Communication using the serial port interface Serial communication is the most common low-level protocol for communicating between two or more devices. Normally, one device is a computer, while the other device can be a modem, a printer, Arduino®hardware, another computer, or a scientific instr...
string[] portList = System.IO.Ports.SerialPort.GetPortNames(); for(inti = 0; i < portList.Length; i++) { stringname = portList[i]; comboBox.Items.Add(name); } 还有一种通过调用API的方法来获取实现,可以获取详细的完整串口名称,对于USB-to-COM虚拟串口来说特别适用。
Also, here you should create a virtual COM port by specifying a port name and checking the “Create as virtual port” option. 5 Click “Create client connection”. Once you established a client connection, all data from the real COM port of your server computer will be forwarded to the sp...
You use the GetPortNames method to retrieve the valid ports for the current computer.If a SerialPort object becomes blocked during a read operation, do not abort the thread. Instead, either close the base stream or dispose of the SerialPort object....
It can be used in the design of application to work with theserial port. 这里能够被用于应用程序需要与串口工作. 期刊摘选 Meanwhile, gyroscope and odograph transfer course angle and distance respectively to the computer byserial port. 同时, 陀螺,里程表等也将目标的航向信息和运行距离结果通过串口传到...
The term “data set” is synonymous with “modem” or “device,” while the term “data terminal” is synonymous with “computer.” Note The serial port pin and signal assignments are with respect to the DTE. For example, data is transmitted from the TD pin of the DTE to the RD pin ...
