Deleting Ports in Windows.
The Delete button can be used to discard the entries of
ports that have been removed from the system.
Note. Due to problems with the standard Windows Serial
Ports Applet in the Control Panel Make sure that there are no
gaps in the numbering of the first four serial ports, COM 1-4. If
necessary leave a “ place holder” otherwise Windows may
automatically reorder the COM port numbers resulting in serious
problems.
Restarting Windows.
Whenever certain values have been changed in the
Advanced window, a message prompting the user to restart
Windows will appear. Once ALL necessary changes have been
made Windows should be restarted so that the new settings may
come into effect.
