portIsFree timeout increased

In windows, assigning a port may take a little longer than previously assumed value of 2000ms.
I am using Windows 10 1903 64bit, and it takes about 3000ms to initialize a port.
I increased the timeout to some higher value (9999ms) to give a little more space to Windows to initialize a port to use with the app.

This patch probably solves issues #48, #54 and #70
