I'm with victor, victor can be, don't know other method

CodePudding user response:

Should be able to, it can not directly call API,

CodePudding user response:

Open a different serial number bai, what's the q?

CodePudding user response:

Virtual serial port and the actual serial port using method is the same, open a different serial number,,

I usually use pcomm. DLL do a serial port to send and receive procedures, relatively stable

CodePudding user response:

I have is a serial port communication directly call API to construct... Several major API context first touch after cooked... You will find actually not difficult also... Is the biggest benefit of master degree is high...

Experiences: some hardware parts of the equipment itself is defective... Can make a program to test to rule out...
