Question
1 | Why I can not add a COM Port in Windows Vista platform?
2 | Why I can not open the COM port mapped to IPv6 address?

1. Why I can not add a COM Port in Windows Vista platform?

| “Run as administrator” is a security concept introduced into Windows Vista in an effort to limit the ability of non-administrative programs to compromise a computer. Programs not running as administrator are locked out from modifying system folders and portions of the Windows Registry, adding routing entries, etc. This will cause some operations of NPort Windows Driver Manager function abnormally. A program can be “Run as administrator” by right-clicking its icon or shortcut, and selecting “Run as administrator” from the pop-up menu as shown below, rather than simply double-clicking the icon.

2. Why I can not open the COM port mapped to IPv6?

| There are two types of IPv6, one of them is link-local type which is started with “fe80”. The other one is global type, for example: 2001:a304::00ab. If your mapping COM port is mapped to the link-local type, you will also need to configure the interface index to tell system which network interface should data be routed to for this COM port. The “Interface Index for Address 1” setting is for the “Address 1” in main program list, and “Interface Index for Address 1” for “Address 2”
