serial-port

问题 I'm trying to compile this code where the .pro file includes a QT += serialport gives me a Project MESSAGE: Warning: unknown QT: serialport error. Without Qt, I would use CMake and install the package via vcpkg, Conan, HomeBrew, or something like that. But not sure if Qt has its own package manager. I would appreciate it if you could help me know what is the most canonical way to install and include this library. P.S.1. In the comments, I'm being told that I need to use Qt's Maintenance Tool,

问题 In serial communication, ReadFile doesn't return until reading as many as sizeToRead parameter. It is so weird, because actually until yesterday, it works normally with same code, same laptop, returning though it doesn't receive as many as sizeToRead but any bytes. But today my code show weird symptom like this. serialHandle = CreateFile(L"\\\\.\\COM1", GENERIC_READ | GENERIC_WRITE, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0); DCB serialInfo = {0}; GetCommState(serialHandle, &serialInfo)

问题 I'm starting a new .NET Core 3.0 project in which I need to access the System.IO.Ports.SerialPort class. The documentation I'm reading on the class shows that it is applicable to .NET Core 3 ( see the bottom of https://docs.microsoft.com/en-us/dotnet/api/system.io.ports.serialport?view=netcore-3.0 ). However when I add a using statement to my class it isn't able to resolve System.IO.Ports. Is there some additional step that needs to be done to reference the SerialPort class for a .NET Core 3
