Hello all,
Using CreateFile("COM...".) it's easy to detect a serial port that's
physical present in the computer. (COM1 etc)
However when I try to open the USB-to Serial Port (COM11 etc) from my GPS
CreateFile fails.
Does somone knows another way how I can detect those virtual ports?
Thank's a lot!
Regards,
Anton
