[patch modified] doesn't recognize multiple comm ports in Win 7 - issue	#2783

Description of the problem in the MSDN:

https://msdn.microsoft.com/ru-ru/en-en/library/aa363858(v=vs.85).aspx

"To specify a COM port number greater than 9, use the following syntax: "\\.\COM10".

This syntax works for all port numbers and hardware that allows COM port
numbers to
be specified."

But there is not quite right :) They write "\\.\COM10" it's not going to work.

Correctly so: "\\\\.\\COM10"


I tested on Win7x32, COM > 9. Work correctly.

Added fixes to the drop-down list of ports.
In the name of the port removing unnecessary characters for the user's convenience.
