Impossible to connect to serial port which name has 2 digits at the end (comXX)

[valentin tihomirov]

I can open any com port in range COM1 to COM9 but all attempts to open ports
named COM10, COM11, ... fail with (Win32 LastErrorCode 2, 'The system cannot
find the file specified'). I'm experimenting in Windows 2000.

Open it with name \\.\com10(11) ( look at Q115831 of MSDN)
