FAQ and Known issues

Q: I want to control (create and delete) my virtual null modems.

A: You can do it with help of the command prompt.

 

Q: I can't open a virtual serial port.

A: If the "CreateFIle" function within your code uses the "COM%d" format string as a file name then you can open COM-COM9 ports only. You should use "\\.\COM%d" instead. In this case you can use any virtual serial port number.

 

Q: How to enumerate virtual serial ports?

A: If you need to enumerate virtual serial ports only then you can use SetupAPI functions and search all devices for class GUID {487ECAF4-213D-4d17-AA07-2F91078B619D}.
