Com port numbers?

COM Ports are necessarily serial ports which are used for serial communications physical interface through which information transfers in or out one bit at a time. Usually it is the operating system that assigns the port number for these interfaces. If the a moment ago installed PCI card with 2 com ports are assign as com 7 and 8 consequently you can assign them with a different port number resembling com port 1 and 2, assuming these ports are not in use. You can do these lower than the Device Manager. You can also interchange the com port number if ever ports 1 and 2 are in use.
