I use the USB serial port should be able to support 230400, but when I was in initialization CMSComm rate (m_cMsComm. SetSettings (" 230400, n, 8, 1 ");)
If you choose 230400 will tip: "Invalid property value", is there a way to achieve 230400?

CodePudding user response:

Try 256000
Turn the USB serial port of the general will also have the SDK
Or use threads and API Serial Communications in Win32 stronger commonality
