Qextserual can't detect virtual com-port

[blm]

I don't use this alpha version of Qextserialport.

You can scan a list of QString("COM%1").arg(i) and try to open the port: if you can open it, there is an available port. On Linux you can query the list of /dev/ttyS* and /dev/ttyUSB*.

thanks, but i have got the list of com port information, but except for the vitual com port..
